The Sharp Zaurus line of Linux-based PDAs are some of the best around and I really liked the clamshell form of the SL-C3000 I recently reviewed . Sharp has released the next version of the "little laptop", the SL-C3100 and it looks another winner. The sleek black body of the new Zaurus looks pretty good and less iPod-like than its white predecessor and it has all the nice features of the earlier model with increased memory. Most importantly the 4 GB hard drive is still there but unfortunately there is still no integrated WiFi or Bluetooth. I don’t know why Sharp won’t at least put WiFi in these things. The C3100 will only be released in Japan so if you’re located outside the land of the rising sun you’d better cozy up to your favorite importer.
