Not to completely jack the thread, but I like Windows Mobile, too. Specifically, all the freeware and other software available for it.

iPhones are great for people that don't know any better (and the UI is amazing), but there's just something to be said for a phone that allows me to stream my home TV cable box/DVR, run planetarium software and use a weather app that updates itself every two hours with any radar map on the internet I tell it to update.
