Nintendo 3DS isn't bad. It's not "revolutionary" other than it's the first to do 3D w/o glasses. From a "WOW!" factor, I'd give it a 4 out of 10. You do have the ability to scale up or down the 3D-ness of a game so that helps.
Some games are better than others, Steel Diver is pretty cool, but others are more gimicky. From what I understand, the newer releases are much better. I don't think there's much difference in price, so I guess there's no reason not to buy one.
One thing though, 3DS does not play the first generation games.
