Ok, time has almost come to retire the Wii, and whilst my son wants the Wii U (so he can play Mario Kart etc), I'm not convinced
I've looked at a couple of comparison, and this one sums up the specs versus the 3 pretty well here
So, what's everyone's thoughts on what I should get my son for Xmas ?
PC: My nieces were online with FaceBook from an early age, don't know about SAFE chat-rooms, but there might be some. Also education experiences are available, that can't be got from a console.
Wii's are more child-orientated. Less violent content. Don't worry about whether it's the latest console. Save your money for more games etc.
Keep activity in the lounge room so social interaction still happens.
Is he any good at playing them? Some kids like to watch the champions play. (Maybe you?)
Is he also into ANGRY BIRDS? My nephew really liked this from a young age (5 YO), until his parents worked out he was making purchases on the mobile phone for this, because he made all the free levels.
Read the above suggestions from everyone, but try to put aside allegiances.
