Perhaps it's not surprising, but what this video from The Clan of the Grey Wolf reveals is that much of the tech behind the Wii U's GamePad is stuff you may already be familiar with—only used in a clever, innovative way.

As the video points out at the start, this seems to be a thing with Nintendo hardware, where they use proven tech to create something completely new.

What I like best about this video is that it dives deep into technical things, but does so in a remarkably approachable way.
