As a side note, the best buy by me had not sold one at noon (San Francisco)... they had reps from google in-store doing demos, but nobody buying. As others have said... two issues, it's a Galaxy S, nothing new, and it's T-Mobile, nothing spectacular.
Next phone please. Comon, make SOMETHING to beat my iPhone so i can get a new phone, hehe.
The odd thing is every android manufacturer has the same 4 buttons on the bottom of the screen, and the Nexus S decided to follow suit, but change the order of the buttons. Not much propriety there for an android platform
