You realize how terrible they are compared to a real computer.
Depends what you're doing.
I've found nothing I do that a tablet can do better than a traditional desktop/laptop. This may not be the case for a lot of people, but I used a tablet for about a month while I was waiting for a charger for my netbook. Haven't touched it since, it just makes everything I do more difficult and time consuming, or offers no advantage. I'd honestly sell the thing if it hadn't been a Christmas present.

You try to swipe on the screen of your laptop.
You're sitting at a desktop and you hit the space bar twice at the end of a sentence, expecting a period.
You expect your computer to auto correct every misspelled word...
When you think the game you are playing on your Mac would be easier if it had tilt control.
Depends what you're doing.
I believe since Lion, autocorrect became active by default.
