I didn't really want a clamshell design because I don't like fumbling to open those things up, and most of models available right now like that look like one drop to the sidewalk would take them out entirely. This thing looks more like a cell phone stuck in a Fluke Multimeter protective clamshell.
(These things are nearly indestructable)
Anyways, I got another one (not the same model) for my wife, and now I just have to wait for them to start working. Hmmm. I remember my AT&T phone worked out the door from when I bought it. Not having these things work for the next couple of hours is annoying, and not very "new customer" friendly.
