I dunno, I moved from a Samsung Android phone to an iPhone 4S at Christmas and I can't say that I have missed much about the Android system. The iPhone does take a bit of getting used to and there are pluses and minuses for both operating systems. I have recently jail-broken my iPhone 4S mind you, so I have done a few customisations and tweaks that I wouldn't have been able to do otherwise, but overall I am happy that I made the change and I love my iPhone 4S. But it is horses for courses I suppose...
