Correct comparison would be iOS vs Android.
I'm for Android. I like it, can have gadgets on home screens instead of a huge list of Apps and you can customise the very launcher to an extreme level. I have a HTC Desire phone and a Samsung Galaxy 10.1 Tablet.
Can also develop for free on Android without having to pay for the development environment, the right to develop and then the bribe to ensure your app gets through their verification process.
I also have an Ipod4 and I laughed so hard when I saw Apple IOS 5 beta took the pull down menu from Android
