Windows Mobile smartphones (Standard Edition) can be actually powered down. However, Pocket PCs (Professional & Classic Editions) are not really off unless the battery is pulled out. So, if you have an anniversary event (birthday, wedding anniversary) set in contacts, it wakes up at midnight and sets of the audible alarm (if that is turned on which is usually the case). I’d like to know which braindead idiot at Microsoft decided this is a desirable behavior.
