And IIRC, the Wii is the only console that has been making a profit on hardware since launch.
But it seems they really hit a home run this time. It's more or less ignoring the market segments the other two are going for and going for kids (like Nintendo does normally), but at the same time, finding a market that seemed to be unexpected. But they definitely managed to cash in once they found out the senior market was interested.
Say what you want about the games, but the controls are easy to use to a new player, unlike the mass of buttons on the 360/PS3, and most of the time what's going on onscreen is easy to figure out at a glance. Those two things, (or lack of) are the reasons some of the people I know can't get into gaming but they love to play the Wii.
