If you don't have an iPad already then get 2, but if you have 1, then do not upgrade unless you want a camera for video chat. The quality of the still camera is rather poor.
From what I have read from the rumor mill I think it will be worth upgrading from 2 to 3 becauase it appears some of the upgrades will genuinley make a big difference.
