Current 240Hz tv's dont even accept a 240Hz source, they just scale the video from 24-60 Hz to 240 Hz.
At least in America you can buy in sets of 400, in the UK it goes up in 500s.
800+400=1200
Both are aimed a different markets. If your looking for more hardcore games then the PSP by far, but it you want more casual games then the DS.
the only thing close to a gaming netbook is the alienware m11x.
It's all good for me.
