Windows didn't get the top position in desktop usage because it had such a good UI. Neither does the iPad really work well as a desktop replacement. It's all about laziness. If (for whatever reasons) I use this device for most of my tasks for most of the day, I have an incentive to use it for all of my tasks. This might lead to a "challenge" but at least I don't have to start up the laptop with Windows or boot into Windows to get my tasks done. And sometimes, you just decide that this "important" task wasn't that important after all and just work around it.
