About to go out tomorrow and I hear great things about both - major worries on the 7100g:

Seems cheaply made - a little too light compared to 7290
I bet I will get used to Suretype, but I hear that most shortcuts do not work
IS the screen much smaller than others?
All of the voice quality comments I have read.

Any users out there that have used both or have had other experiences, please share and THANKS
