Email Icons Don’t Show Unread Email Count
Unlike the iPhone, my Nexus One does not show the number of unread messages on the mailbox icon.

Screen Sensor Misalignment
About once a week, I have to restart my Nexus One because the screen sensor is misaligned. (Pressing an “R” yields a “D”, for example.)

Battery Life Sucks
The screen (which is very nice) sucks a ton of battery juice. With moderate use, I have to charge it twice a day.

Battery Gets Pretty Warm
When charging, the batter gets pretty warm. Not a huge deal, but I never experienced that with my iPhone.

No Hard Switch for Silent (on the N1)
Without a physical switch for “silent” (like the iPhone) you must set each app to “mute.” Example… say you’re bored silly during a presentation and whip out your phone to play a quick game. The ringer is set to mute, the media volume is set to mute, but the game you launch ignores all that… it happily starts singing all its startup sounds. BUSTED.
