Got it today and it definitely feels more durable and stronger. I had to do a system transfer in order to get the eShop games/demos I downloaded, but other than that, it's great. The screen size is great too and the system fits so comfortably. The only complaint I have is the stylus is too slippery at times.
Still rather sore that my original 3DS only lasted two years. I know I won't get a Nintendo system at/near launch ever again.
