I am on Andriod (X10 Mini Pro).Prefer it over iPhone because I didn't have to sell one of my kidneys to buy it.
Rooted my phone a few days ago since SE wasn't ready to give a Android 2.3 update to the X1o mini pros.
As for apps, I hate almost all the games that come out for smartphones mainly because they lack gameplay. I was really excited when I bought a smartphone simply because of the new capabilties, but what did I get? A bunch of pathetic touch screen games like throwing paper in a basket and a sh*t Crush the Castle clone. The only games I play on my phone are some GBA games using an emulator.
