The difference doesn't IMO justify the price; I still think the iPad 2 is great (most definitely the price).
This btw should surprise some people (especially, those that think I'm such a fanboy)
The screen on the iPad3
IMO not so much of a fundamental change as was the iPhone 3 to iPhone 4 retina display -- so not a sure bet.
The GPU improvement
Not fundamentally noticeable change
The back camera
Very much for me is a waste; I much rather would have preferred a high res front camera for Skype, FaceTime.
Weight
It's heavier, you finally get used to it, but feels like a step in the wrong direction.
Thicker
Yes it's thicker than the iPad 2, also feels like a step in the wrong direction.
Heat
The new GPU puts out more heat, so heavier on battery, and subtlety less comfortable for games.
Apps
Not enough exclusive apps.
Summary
I say wait for the the 4th iPad, or
buy the cheaper one...
FYI, I've had the 3rd iPad for just over a month and still have my iPad 2.
Note: even though I can be honest about less than ideal new kit from Apple, doesn't mean tomorrow I'll be using Windows; that's a stretch too far
Oh I'd also suggest you buy local, the prices are not that high compared to international markets, unless of course you claim the tax back

, and don't declare
