Gratz man. If I watch a video or something on mine battery drains faster than busta rhymes "rapping"
Go Android.
That way you wont be restricted to iTunes and you can use whichever store you like more or less.
There's more customization and you don't have to jailbreak to install third party applications.
Among the most obvious reasons, price for one, you get more hardware for the money.
If you enjoy toying and altering stuff, then Android is heaven.
