I don't get the idea of "don't buy this one, wait for the improved version!". There's always gonna be another improved version a couple years later; if you won't buy it until they stop putting out new and improved versions, you'll just be waiting forever.
It's an issue of whether the device is even worth owning before the remodel. Every system I've bought within the last ten years has been a redesign, not because the "improved versions" were necessarily that much better, but because those systems didn't have enough games to warrant a purchase before the redesign. Why buy something you're not going to use all that often when a better version could come out later? And then there are those who buy every iteration of a product at launch. That's an idea I don't get.
Granted, this doesn't look all that much better than the standard 3DS. But that's the other big advantage of waiting for an updated version: the earlier iteration should drop in price. Woohoo! Now if only the 3DS had a few more games...
