The problem I have with Android is the fact that the app store is garbage, with only garbage apps. The OS is awesome and way better than iOS but Apple's app store has all the good games.
Hardly?
Temple Run, social network apps (facebook, twitter, what have you) all of the angry birds games, tiny tower, minibash, netflix, Cut the Rope, Words with Friends, Draw Something, Steam, Skype.
These are all from my phone that I can assume are well known. Note that this is only from my phone. I've browsed the iPhone's game market and I couldn't find much that entertained me that wasn't ported to Android already.
