I just played with the Google Nexus One for a few minutes, Here’s my report:

– It’s extremely thin

– It’s much nicer looking in person than in pictures

– There’s a 4 GB micro-SD card installed

– The battery capacity is 1400 mAh

– The screen appears to be OLED (same size/resolution as the Motorola Droid)

– 3G works on T-Mobile USA :)

– I can confirm that there’s no 3G on AT&T (EGDE only)

– It’s definitely unlocked

– It’s super snappy! Faster than the Droid…

– There’s no multitouch support in the browser or in Google Maps

– There’s no dedicated camera key, but it’s the same camera interface as the Droid

– The trackball can be used to focus (like on other HTC devices)

– Low-light performance is decent, but the flash is weak

– Calls are routed the normal way, not using data (VoIP), and sound fine

– The home screen is divided into 5 panes (like the custom interface on the HTC Hero Motorola CLIQ)

– It’s using a micro-USB connector for data/power

– There are some gold contacts at the bottom edge, for a dock perhaps?

– Did I mention it’s fast?

Sorry, I was not allowed to take pictures (the one above is from the intertubes). That’s it for now :)

Update: I now have my own Nexus One.
