Aside from no ability to control with IT policy?
What phone do you use and why?
Me = t-mo dash. I gave back the Shadow because of the keyboard, having to open the slider to unlock the phone very 15 mins, and sucky battery life.
The dash battery is going strong after two days, and the KB is just fine for my fat fingers. I miss my SDA, but the dash screen is as bright, tho wider.
