jkOTR review- Sharp Zaurus SL-C3000


Zaurus_screens_013Sharp has always been an innovator with the Zaurus line of PDAs and the newest member of that family is no exception.  The Zaurus SL-C3000 takes the utility of previous generations and extends it even further.  The C3000 is a clamshell device that resembles a miniature laptop when opened and has a bright vivid screen that is wonderful to work with.  Perhaps a more fitting description of the Zaurus would be that of a convertible Tablet PC since the screen swivels and folds back on the keyboard to allow operation in a more conventional slate format.  Using the C3000 either way it is apparent that Sharp is clearly the leader at innovative PDA design.

The evaluation unit I have been using was supplied by Dynamism as the Sharp is only sold in Japan.  Dynamism has done a good job converting the Zaurus to English and as a result there is not a lot of evidence during use that the device was originally Japanese only.  I get asked if I recommend getting Japanese devices like this from an importer and if it is worth the additional expense and my answer is a resounding yes.  While some people can convert a Japanese gadget over to English it is a path full of pitfalls and it is usually best to let the experts handle that when possible.

The package

Zaurus_screens_007The first thing that struck me when the Zaurus arrived was how small the box was.  The size of the box is always a good indication of how small the device will be and this was certainly true of the Zaurus.  Unpacking the unit found very little in the box, the Zaurus unit, power adapter, Japanese manuals, USB cable and a couple of CDs.  Dynamism had also included a couple of pages of useful information about getting started with the Z.

Zaurus_screens_008The Zaurus itself is a glossy white plastic very reminiscent of the iPod.  Close inspection proves that the construction of the Z is very sturdy and well executed.  The device just looks perfect in every way.  It is also heavier than I expected, not that it is too heavy just that it feels heavier than the size would indicate.  This is probably due to all the goodies that Sharp has put in the little jewel.

Using the Zaurus

Zaurus_screens_001The SL-C3000 is heavier than expected but fits in the hand so well it is quickly apparent how good the design of the Z really is.  It is a tad big in the hand in slate mode but again easily handled and the thoughtfulness of the design is reflected in the control placement.  The Zaurus defaults to landscape orientation and is obviously intended to spend more time in the clamshell configuration with the keyboard available for use.  The swivel screen is very easy to activate by simply swiveling the screen around and folding it back over the keyboard.  Instant slate mode makes the Z even more useful to the user and the clamshell when closed completely protects the screen and the keyboard.  The VGA screen is simply amazing and is so bright and vivid it is easy to see that Sharp’s monitor technology has been incorporated into the Z.  It is very easy on the eyes even with prolonged use.

Sharp chose to exclude integrated WiFi in the C3000 and it was the only major disappointment I had using the unit.  While it is easy to add WiFi or Bluetooth via the CF slot it would make more sense to build it right into the Z.  I used an Ambicom CF WiFi card for my evaluation and the card was auto-detected and configured as soon as I plugged it in.  I just had to configure my WiFi network settings and I was off and running.  The WiFi worked very well and I had no problems at all the entire time I was using the Sharp.

Sony_sharp_009The keyboard is an area that Sharp obviously put a lot of thought and it really augments the user experience.  The keys are real keys with good tactile feedback (and optional key click sound) and are great for lots of text entry.  It is easy to get up to 40 wpm with this keyboard, it’s that good.  Sharp has included a full complement of keys in a standard QWERTY layout, and you also find some special keys that launch the PIM functions.  On the lower right of the keyboard is a round trackpad with an OK key in the middle, and a Cancel key next to the pad.  The trackpad works very well and made navigation in clamshell mode very easy to do.  The keyboard works so well that after a little practice time using the Z in clamshell mode is just like using a tiny laptop.

Sharp has incorporated a lot of little touches that make using the Z very easy no matter which configuration the device is in.  There is a thumbwheel control for one-handed use in slate mode, OK and Cancel buttons on the back of the unit, and the ON/OFF button on the front of the Z is recessed making it unlikely you will accidentally turn off the device.  There is a little HDD activity light on the hinge of the screen that is a good way to tell if the system is doing something.  I quickly got used to this and wish all PDAs would incorporate this simple yet effective indicator.

Zaurus_screens_003Zaurus_screens_004The PIM programs that are included on the Sharp are very basic and have all the standard features you normally expect.  The Contact program will not sort contacts alphabetically limiting its useful completely (it sorts on the Japanese alphabet).  You certainly want to pick up a third party PIM application to do serious PIM work on the Z.

Getting connected

Zaurus_screens_006_1Connecting to the internet is very easy to configure once the WiFi is working and Sharp has included a couple of programs to make the user productive.  The Email program is very easy to configure and provides a good interface and all the basic functions you expect of an email program.  For browsing the web Sharp has included Netfront 3.1 and if you have used this program on other PDAs you will feel right at home.  It worked just as well and had identical features to the version I run on my Windows Mobile Pocket PC.  Netfront has a couple of good techniques that fit complicated web pages to the small screen of the Zaurus and it is possible to view virtually any site on the VGA screen.  While some pages rendered the text very small usually this was not a problem.

One of the first programs I downloaded and installed on the Sharp was Opera.  Opera is a great mobile browser and it was super to use it on the Z.  The Opera browser is very fast and really utilizes the small screen to the maximum.  I never used Netfront again once I installed Opera, it’s that good.


Sharp includes a version of Intellisync on the CDs that come with the Zaurus but the program is in Japanese and thus virtually impossible to use for English speaking users.  You can install an English version that you can get online but you must be sure and install the hardware drivers that come on the Zaurus CD.  Once doing this Intellisync runs in English and will synchronize the Zaurus PIM information to Outlook or Palm Desktop.  I had a lot of problems throughout my evaluation of the Zaurus with this synchronization which might be due to my complicated Outlook setup on the desktop.  Some users report no problems syncing with the desktop and others are never successful getting their PIM data onto the Z, so this is an area that needs some improvement.  Once the drivers are installed you can connect the Zaurus to your desktop using the included USB cable, and the Z appears as a removable drive on the Windows desktop which is a handy way to get files back and forth.  This is much easier than using ActiveSync on a Pocket PC.

Showing its Linux roots

Zaurus_screens_002It is important to remember that the Zaurus is a true Linux box and if you like puttering around in Linux you will love using the Z.  It is not just cool to see the Linux terminal window displaying on the Z, it is just as functional as on any other Linux box.  You can do virtually anything on the Sharp you can do on your Linux desktop, and this is very powerful indeed.  You have complete control over the Linux environment and can run many Linux programs on the Z.  Software is installed as packages and there is a good program for installing or removing software packages on the device.  I should note here that due to the C3000 being so new a lot of programs I downloaded and installed on the Z would not run, even though they would run successfully on the C3000’s predecessor, the C860.  It is only a matter of time for updated versions to start appearing for the C3000.

The Qtopia interface puts an attractive face on the Sharp as it looks really good while being very functional.  Users who opt to just work on the Sharp using the Qtopia interface will find it like any Palm or Windows Mobile Pocket PC in form and function.  While Linux allows for the installation of other interfaces for those who don’t like the way Qtopia works, such as Cacko or pdaXrom, it is important to note that neither of those interfaces have been updated to work on the C3000 yet.

The Dynamism conversion

All in all I was very pleased with the Sharp Zaurus SL-C3000.  It is pleasant to use and the battery life is very good, even with the Microdrive.  The Dynamism conversion to English is very thorough and well done.  They have supplied two different modes for non-Japanese users.  The Hybrid mode operates in mostly English but a lot of Japanese functionality is still available, such as translation from English to Japanese.  The Full English mode is just that- Japanese has been removed from the device and virtually all program menus and screens have been converted to English.  This is the mode I used all the time during the evaluation.  Switching between modes is a simple script execution followed by a reboot.

New Zaurus owners can find a wealth of information online through users groups and support forums.  Compatible software is available from a number of sources and is usually free, one of the big advantages of the Linux operating system.  The Zaurus Users Group was my favorite source of HOW-TOs, support forums, and software downloads and I highly recommend that to all Zaurus owners and even those who are trying to decide if the Z is right for you.


The Sharp SL-C3000 is a powerful, innovative PDA that begins to infringe on the territory normally occupied by laptops.  The design shouts quality from every surface and the device is just perfect for working on the go.  Using the Sharp as a tiny laptop is easy to do given the great keyboard, and switching over to a slate configuration makes using it as a traditional PDA very easy.  Either way you will find yourself getting some real work done with this device, even though its small size would belie that.  The Zaurus is a good device for those who are Linux enthusiasts who don’t mind tinkering around with the hardware and software, but novices would probably be better off sticking with either a Palm or Windows Mobile based device.  The only two complaints I have with the C3000 is the lack of WiFi and the way inking on the screen works, which could be better.  The Zaurus is currently $819 at Dynamism where you will also find accessories available.

Configuring is not so clear for me!
There a lot of square in place of characters in the interface to configure Wifi.
Is there a place with a step by step tutorial?

Doug Kern

Just got the new SC-3000 and I’ve heard that it is possible to Sync with Outlook in W2K though I have yet to find the steps or a document that explains it. Anyone have any ideas?

Julian Fondren

It’s a bit silly to bring up the UX50 — that “T EARLY-ADOPTERS *** YOU KTHXBYE SONY” device gave me so many problems: deafening screen whine, are-we-still-on-mains?-oops-guess-not-bye memory crashes, and then repeated, mostly-inexplicable crashes apparently to do with the m68k emulation and my pleco.com dictionary. I paid nearly 600 USD for a device which went completely haywire in a few months, from a company that doesn’t give a damn.

Even my developer’s edition SL-5000D has always worked perfectly.



How do you use a mouse (or keyboard keys) to navigate (point) in X windows?




I just received my zaurus. I tryed to find a suitable version of opera web browser, but didn’t succeed. Would you have a link to the right version?
thx in advance.


I hope Skype for Zaurus to be released so bad! Pretty please!!


I bought a 700 a monthbefore the 760 was announced.
I bought a 760 then. Later I also purchased a 5600.
I prefer the clamshell layout and design.

See http://www.pdaxrom.org/ for those who complain about not a full linux.

With standard 760/860(3000/etc) and Qtopia, you can load
EVERY application that comes pre-installed on the device — into ram… instant off, instant on, all apps in RAM. It’s really nice.
However, I prefer to run full/straight linux and X.

The screen is beutiful, sharp and bright. The clamshell keyboard is easy to use, even in the dark — and you can get 40+WPM, etc.


quake, doom (at the same time, etc — see screenshot) … emacs, firefox, thunderbird, emacs, gimp… gcc/g++/perl/python, ssh, irc/im, games, etc.

In response to David’s question about cell providers:

While the drivers may not be available yet, you will be able to use wireless cellular for this device. The Zaurus 860, which I have, which is the predecessor of this, supports many wireless cellular options.
I can buy a socket digital phone card, which plugs into my cell phone with a cable, and connect to the internet(there is a socket dig phone card for many types of cell phones).
I can use a socket bluetooth card, and use any cell phone that has bluetooth to connect to the internet – that includes verizon – cdma, and cingular and tmobile – gsm.
I can also buy an audiovox rtm8000 and use it as a cell phone directly with any gsm provider. The rtm8000 is the only one I haven’t personally used. The rtm8000 is also the only one that I know of that you could actually use it as a real cell phone to make voice calls.


ps- I can’t check this site quickly, so if you want to followup with me, please :cc my email address.


A few answers:

I ran the Sharp pretty heavy and it always lasted all day. I felt the battery was no worse than any other PDA. It didn’t seem like the HDD was that big a factor on the battery life.

There are no wireless cards (GSM or CDMA) that work on the Sharp that I am aware of.

Don’t know about dropping it and the HDD. Dynamism would not be too happy with me it I ran that test. :)

Tim Hardy

Good review thanks. Can I second the request for more specific info on battery life. I had an early model zaurus which was beautiful but the battery life was so poor that it was unusable as a PDA. The experience has put me off the line – even though I’m still absurdly excited by the idea of have a linux device in my pocket.

No one

What about if you drop the thing?

I’ve used PDAs for years and they get dropped all the time even by careful users. Will the HDD break like the iPod’s do?


Hector, aside from the supposedly superb screen and keyboard (areas where the Sony UX line came up short), the big thing about this device is the integrated hard drive. Combined with the flexibility and power of a linux base, 4Gb in such a small form factor gives a lot of potential.

The biggest disappointment of this unit, then, has got to be the lack of wireless connectivity. If they ever `fix’ this, I’ll be a customer…

Jan Moons

As a reply to Hector. To be fair, the zaurus sl-c700, released over two years ago, had the same design. So sharp certainly beat Sony to it. You can’t hold it against Sharp that they don’t change this design, because it is perfect for its purposes. Even the MDA 4 will start to adopt it and I expect more to follow.

Hector Velez

It looks cool and it’s great that it runs a linux OS but theres really nothing inovative about this PDA. Sony had the Clie Pegux50 that looks very very much like this PDA except maybe a bit smaller 2 years ago. And the Price tag is that of many entry level laptops so maybe I’ll pass!


Can you report on MP3 and movie playback? This is the most likely use for those 4 gigs. Do higher rate files play that much better, at what rate do things bog down, and can this Z play variable rate MP3s (which older Z’s couldn’t)?

And any specifics on battery life? Using Wifi and not, using the hard drive heavily (like MP3/movies) and not.

Many thanks! I’m starting to look seriously at this Z now.


I wonder what ever happened to the Linux version of RitePen that was announced in August 2004?

With all of the great reviews, I thought that this would be the best handwriting recognition software for Linux/Qtopia.


Steve, I didn’t comment much on the inking (other than complaining it could work better) because I was never successful at getting the inking to work very well. The Z uses an ink entry box at the bottom of the screen for inking when in portrait mode and it is obvious the inking s/w was written for entry in Japanese. It’s not like Grafitti in that you enter letters normally and no special characters must be learned. I had so much trouble trying to get good results with the stylus that I eventually gave up and just used the keyboard. Fortunately for the Z the keyboard is excellent.


I didn’t see much on the inking. Does it have some kind of Grafitti-type input? It couldn’t have handwriting recognition, could it? What were the problems? Does it come with a stylus?


I guess it depends on what you mean by compromises. The Zaurus does what it does very well- PDA + extended document manipulation with the KB and Hancomm apps. It’s not in the same league with the Sony or OQO so I don’t think a comparison with the Z would be a fair one. I would be happy to review the OQO but I don’t think it likely they would supply a review unit since they only seem to give them to big media outlets. Plus, I have not been shy in my criticism of the problems I have heard with the early units. I could not live with the 800×480 resolution of the OQO screen- it just doesn’t display enough info for me.

I don’t consider UPCs to be PDA replacements so I am not as concerned as some about a device being as small as possible. I am more interested in devices that are complete computer replacements to alleviate the syncing issues once and for all.


So what are the negatives outside of Syncing?

On every PDA, PPC, and uPC, there are compromises, what are they on the Zaurus?

Qtopia is embedded Linux, so it doesn’t run full Linux, what uPC applications/functionality did you miss using the Zaurus?

How was it’s overall use compared to the Sony U750P?

Now I wish OQO sent you a demo, so you could compare all three devices, best application, etc.

Maybe you can collaborate with Ultranote on this?

Very good article! Thank you for sharing it.
