But if I poured him a beer everytime he made a new achievement on the Wii Fit, it would slow down his weight loss

Also, even though I'm not a big fan of Nintendo one thing I will give them credit for, and Paul touched on this earlier, they are always trying out new things.

The PS1, PS2 and PS3 are all the same console, just each one is an upgrade from the previous. Same for the Xbox and Xbox 360.

But Nintendo always try new things - there's a reason why the Wii was orginally going to be called the Revolution.

But alas, I still prefer playing the PS3 :P BUUUUUUUUUUUUT on the PS3 you can't play on Pokemon AND on the Wii you get so much more Sonic The Hedgehog games.
