Wii!
It is reviews like this one:
The reason for this is that it is easy: It just works. The first time you hand a Wiimote to someone and they point it at the screen, they know what to do. There's a little hand, representing where you're pointing, and each Wiimote has a different colored hand. Navigating menus is actually … fun, in an odd sort of way. Moving over UI elements with the little hand representing your controller causes a very slight rumble. The controller shakes just enough to give the entire experience a tactile element that, again, I've never seen in gaming before. It's the little things like this that really makes the Wii experience. Turning the Wiimote upside down inverts the hand. They didn't have to do it that way, but they did. Navigating menus is, mildly, fun. One of the first games my cousins played after they'd picked up the controllers was the "duel with their icon-hands" challenge. Odd, yes, but entirely understandable. The Wiimote, and the completely natural movements you make when using the device, require no explanation. When Nintendo went to the AARP event earlier this year, they knew what they were doing; this is the console your grandmother can use as easily as you can.
that put the Wii at the top of my post-holiday shopping list. The focus on the gaming experience and not just the raw video performance is what has distinguished this console from all others. I can't wait to get it!
