What a difference a few years make. Back in 2005, Nintendo was blasted by fans and the press for the lack of HD compatibility for the Wii, a technology seemingly so simple to implement and make impressive use of. Today, 3D is the next big thing and despite being a far more divisive and laborious feature to use, the Japanese hardware maker is tackling it head-on. But it's doing so in the most fool-proof way. There's no need for an expensive new television or special glasses - the 3D effect works as soon as you switch it on, and it's as straightforward and impressive as it sounds.
