I did the same - think it was my first time in an AT&T store -LOL. Other than the Atrix screen looking smaller I thought the screen was good. I compared it side by side to my Viphone and X and did not think it was quite as good/clear as the Viphone but a bit clearer than my X. I really don't need anything better than my X screen - its vibrant and bright enough to use in full sunlight.
I have no idea why they released such a small batter as OEM with the TB -- then came out with a 2700 MONSTER. All we need is a Droid X type battery - or the Droid Extended Slim battery that gives a small boost.
Have been tethering my my TB to my xoom over the weekend - instead of using WIFI - its that GOOD/Fast.
