I'm not sure for everything, but on iOS 4.1 with my iPod Touch (so no, I don't have a modern mobile phone, but this is basically the same) it's much easier to do the things most people do (Twitter, Facebook, email) than it is on a PC. Plus, want to install a game? A couple taps and a couple dollars, and you're ready to play a game within seconds.

Compare that with a PC: find a game online, create an account to download it, spend $20-$50 on it or perhaps just $10-$15 if it's a basic game, wait while it downloads, then step through the installer and if all goes well, you can play your game.

We're all programed to do it, and it's a no brainer for those of us that are used to it, but the iOS model is so much simpler for people who don't enjoy tweaking a machine and just want it to work.
