If you have a Google account all Google applications are automatically backed up. You can buy any phone, switch any phone, switch to any tablet and your Google apps are exactly where you left them. No need to plug into a computer and wait an hour or two to get a backup.
Now, if you aren't rooted and want to back up all your sms, call logs, data and apps there is the app Helium. Same slow backup and restore as itunes.
If rooted, it is no contest. Apple is slow, clunky, and antiquated compared to backing up on Android. This is one of the main reasons to root your phone. You can back up single apps, multiple apps or the entire phone. Between Titanium Backup and ROM manager, you can be up and running from old phone to new phone in less than 10 minutes.
Hmm, how do you enable apps to be already installed, have all user settings saved, game saves, etc? I don't think it snapshots these, but I'm not sure as I haven't used it much.
I don't see how Apple is slow or clunky, it's invisible, seamless. Titanium is fairly complex, ROM manager is very complex if you are talking about flashing and adjusting entire ROM's. We are talking about the unwashed masses here, not about you or me who can figure that stuff out, or even care to figure it out. The ability to not think EVER about backing up your phone is what consumers want, that is streamlined and modern IMO.
