A business partner of mine has one and I played with it for awhile.
The SW that types the word out is really cool, but it does not know the words: stoopsisajackass, *****, assfuck, and assclown (although "no talent" works).
I've had the 7100t for about 7 months and have been pleasently surprised. E-mail and phone work great. It takes a little while to get used to the typing, but, once you do, it's pretty easy.
7100t user, love it. lost my first one and hated going back to a phone while the car service looked for it that I went to the nearest Tmobile after 2 days and bought another on the spot.
