Wii!
I got one. It rocks. A friend of mine works at a Gamestop nearby and held one for me. Karina and I had a coup el of friends over on Sunday and we ended up spending something like four hours just playing Wii Sports. the game that comes with the system. I also picked up the new Legend of Zelda game, but, honestly, as much fun as it is, I think I'm going to be on Wii Sports for a few days, even as simple as it is.
So, in all, great system. Oh, and you don't need a memory card if you decide to get one. There's enough on-system memory to keep you happy for a little while. Also, grab an extra controller and nunchuk, because the system is tons more fun if you can play with other folks. The only thing I haven't liked so far is that the wireless seems touchy. I may be switching to a wired connection for it.
