Trailer vids for new devices always make the product look exciting and trendy and above all social.
My experience with the 3DS has not lived up to any of these. Which is fine, I only bought it for Ocarina and the promise of Majora (which was fulfilled - eventually). I only have a handful of games for it - but I've never had a huge catalogue for any Nintendo device - apart from the Gamecube.
I rarely buy into consoles at launch, preferring a wait and see attitude - last console I did buy into at launch was the Dreamcast - maybe I'm just unlucky - my first foray into mobile gaming was the NeoGeo pocket color - which also got withdrawn a few months from purchase.
Whether it'll be another Wii or a Wii-U I wouldn't like to say at this stage.
