Perhaps another thing to consider is that most of the games in these two consoles are mainly for more mature gamers...... would it be appropriate for your 10 year old nephew (contents like gore, swearing etc)? would it be potentially fun for him or would some of the game be too complex and he'll just give it up?

Also, these are expensive and fragile machines, so if you're getting it for your nephew, make sure he really treats it well...... these machines aren't just game machines anymore, both of them can do a lot more like playing videos/music, chatting, web surfing, its essentially like a PC.....

I've also heard that modded Xbox360s will potentially have their Xbox live account banned if the Microsoft network detects it.......
