PS3 = a Formula 1 race car
360 = a Ferrari sports car
Wii = a kiddie electric car
The analogy is genius, the F1 is the most powerful and expensive of the three, but you can't drive it on public roads (roads =~ games). But it's quite a niche market and hardly anyone has one. The sports car is likely to crash and burn if you try to use it to its full potential (just google for burnt Lambos or Ferraris). But at least it's road legal and it's cool to own. The kiddie cart is simple and fun for kids but severely underpowered and you can only drive it in parks and pedestrian pathways. And grown-ups wouldn't be caught dead in one even if it does look kinda fun.
