I'm a proud owner of the Nintendo Wii and DS.
I used to own a Playstation 2 and Gameboy, but I just couldn't be attracted to those, so I sold them
Anyway, the line up for the Wii seems to brighten a little (no big titles since its launch), looking at the E3 stuff they showed. Super Mario Galaxy and the new Metroid in particular.
Two gadgets are also geekishly cool: the Wii Fit board is an obvious winner to grab hold of the casual gamer and the non-gamers, but this is supergeekishly awesome:

Look how the Wii Remote and Nunchunk are clicked in the zapper. That looks like a very good way to start playing FPS on a console, Operation Wolf style! Let's face it, FPSes suck on the consoles, because of the lame control methods. Pit any experienced PC players against experienced console players and the PC players shoot the crap out of the consolers.
