The desktop dock is sturdy and attractive. Comes with an extra power cord (so you can use the one from the phone elsewhere) and an audio out cable (1/8 -> RCA).
When you cradle the Nexus One, it launches the “clock” app which shows time, date, weather, next alarm (if set) battery charge level and a row of icons at the bottom for Alarms, Gallery, Music and Home. After about 10 minutes, the screen goes black and the time, date and next alarm are shown in dull green (suitable for beside the bed).
Charge time from a completely drained battery takes about three hours when plugged into the wall.
My only complaint with the desktop cradle is the bottom lip that holds the phone from sliding out. It should be 1-2 millimeters taller. Sometimes if you press the screen near the top (like pulling down the info pane), it causes the phone to “pop” out of the cradle onto the desk.
