i had a go on a wii and think its fun but its limited and i'd tire of it.
Horses for courses I guess. The beauty of the Wii is even my Mrs and little one enjoy playing it. It's that simple to use

I'll be investing in a PS3 soon too (at £269 rude not too). I'll mostly use this as a media hub for streaming DivX/Mp3 from the PC and watching blueray DVDs. I'll probably play the odd game too.
