The Great Phone Debate

I've been in far too many discussions about what smartphone people should jump to.  I've seen people argue for everything from iPhones to Blackberries (Right when they were dying).  It's always interesting to see why people choose the phones they do, but I do think that each phone (iPhone, Android, Windows Phones, etc.) serve their own purposes.  So with the announcements of the new iPhones, Android phones, and Windows phones, I figured I would make a short guide based on my observations for this.  As a couple of notes: I have owned multiple iPhones, Android phones, and of course the classic flip phones.  I've used Windows phones and Blackberries that friends have, and have of course looked into each of these based on my needs.
