Wow, did you get the awesome PPC-6700? Yeah, those are COOL. Good choice.
Seen those in action, and yeah, the keyboard buttons are much bigger than the SK3.
I just realized, in my office, we have 5 different QWERTY Sprint phones:
Blackberry 7250 with EVDO (Mine and 2 hearing co-workers)
Blackberry 7520 (2 Deaf co-workers)
PPC-6700 with EVDO (Deaf co-worker, and boss)
Treo 700p with EVDO (Hearing co-worker) upgrading from a Treo 600
Treo 650 (Interpreter)
I'm waiting for my Blackberry 7130e (EVDO capable) to come and play around with, but I love my 7250.
