I agree with Zro... I came from the 8700 over to 8100 and have never used Suretype before. It took a little time to get used to where each letter was presented, but it didn't take long for me to get to a point where I can type at the same speed as a full size Qwerty...especially with 2 hands. With 1 hand I am a bit slower, but with enough practice... I'm sure I will be typing blind in no time.
