Two days of ownership and two big dust particles under the screen. I can live with a little dust (just like scratches), but how much will ultimately accumulate under the screen?

Quick review:
Web - blazingly fast.
Dedicated Send and End keys, great - but I still find myself hitting the Escape Key.
Display - I like the increase resolution, but prefer the "always on" screen of the 7290.
Keypad - a bit cramped (also prefer the 7290) and I have a bad "N" Key - only recognizes about 25% of the time.
Bluetooth - great, no issues.
Desktop software v4.1 - crashed my laptop everytime - still running the original 4.0 that came with my 7290.

I've got 30 days and I'm wavering on the 7290 vs 8700c. Ergonomically, I prefer the 7290 while the 8700c has the cool bells and whistles. However, I'm a road-warrior and for now, the 7290 may suit me better.
