Planning to buy an xbox. I was just gonna go with a 2nd hand that are sold online that are already modified but i have trust issues so im gonna go with a brand new one. But: - im just gonna play backup/burned cds on it - not gonna go online/xbox live (since i dont know what that is) - also not gonna use an ext HDD cause theyre pricey. And im not gonna play that much game either Theres this one store where they sell brand new units that are already modified. Which is a great deal but no kinect. The other shop sells at the same price but with kinect and not modified. my concerns are: - if i buy the non-mod one and pay for a modify service, is that more problematic for me? cause what it that new unit isnt hackable? - im only going for the 4gb one. What does that 4gb even do? Are those only for people who download games online? (which im not gonna do) (and i wanna play gta5 and i heard u need 8gb for that?) - still kinda confused with jtag and rgh. I know they let you play from the hdd. But can they also play backup cd?
