Wow! I was surprised when I woke up and found 30 replies to my question.
It's interesting to see our heritage (ie previous phone). To the person with the BlackBerry, you are abandoning a sinking ship. Welcome aboard SS Android. Full steam ahead! You'll love it.
To the couple of people switching from iPhone, I'm curious what your reasons are.
My wife just upgraded last month from Droid Incredible to iPhone 4s. She has very mixed feelings about her experience so far.
She loves some things about the iPhone (screen quality, camera, smaller screen - she doesn't have man size pockets) and hates others (notifications not as good, lack of a good, free navigation app, Siri - something about another woman telling her what to do.)
I'd like to hear your reasons for leaving iPhone.
