I personally prefer having an embedded modem in my devices. I have tried and currently use both, but dislike having a USB or PC-Card dongle hanging out of my machine as I walk between meetings and conference rooms.

I also prefer the clean look of the internal modem. Not that it is my main driver, but it does factor in.

I installed an internal EVDO modem for my recently purchased 2710p but I didn’t get rid of my USB720 and PC-Card modems. With Verizon’s device activation pages, it takes about 2 minutes to active a different modem if necessary. I feel like I have the best of both worlds.

Actually, I believe you will be in majority here. Why would I buy same device over and over if I could purchase one USB/PCMCIA device and re-use it in any laptop I happen to have at the moment. Two years (of contract) is a pretty long term and anything can happen. Although most people retain their laptops for 3 to 5 years, it still makes sense to keep modem and laptop separately.

Totally agree that embedded 3G devices are not a good thing. Several reasons are explained here: http://www.EVDOinfo.com/embedded

What MID market?
