A trackball seems ok to me once you get used to it. (only tested trackball phones shortly so never owned one) If you use one hand on the screen and the other on the trackball you have a lot of simultaneous control I guess.

I want to buy the unlocked N1 but "Sorry, the Nexus One phone is not available in your country.".
G*d F*ck*n' D*mn*d!!!
The US version wont work in Europe right?
I guess (as usual) that by the time I can buy the N1 you guys will all own an N2 (for half the price I pay for the N1).
