The main reason why I think the 360 is a bad console, not sturdy and support is very much lacking. The entry price is also low enough to lure in many kids, but IMO the console just isn't suitable with all its RRoD, need to pay for online play and DVD drive related issues (including disc scratching, especially prone if to this when the console moves).
I don't expect kids or even most parents to realize the extend of such issues when buying this console.
