it's a good deal. i have 2 myself. the old core system and the newer one with integrated wifi and hdmi port. pretty sure you can get on marketplace with the free version of xbox live. i recommend the 320 gig system though...4 gigs is not enough. as far as using it 'little' idk i leave mine on for hours sometimes. not sure about laptop display.
not sure when the new xbox is coming out, but if you'r eonly going to be playing a few games the 4 gig one probably do just fine unless you're going to download off marketplace which it sounded like you were thinking about, then you would definitely want a bigger hard drive.
Battle is a pure form of expression. It is heart and discipline, reduced to movement and motion. In battle, the words are swept away, giving way to actions-- mercy, sacrifice, anger, fear. These are pure moments of expression.
