1- What is the diff between the arcade and the more expensive models? Hdd size? 2- On the PS3 you can attach a usb flashdrive and watch movies from the drive, or copy them to the hdd. Can you do the same thing with a 360?
Difference is hard drive size. The elite comes with hdmi cable and it's black. Yes you can watch them, no you can't copy them.
Yep, Arcade comes only with a 256mb memory card. You can buy a refurbished 20gb hard drive through Microsoft, or buy a new 60gb hard drive in the store for 109.99. I got the Xbox 360 arcade free through Bestbuy. Had to shell out however for the HD and an extra controller.
Arcade only comes with rca cables.. by the time you buy good cables and an HDD you're probably spending more than the regular xbox. I got arcade and then returned it and got the 60GB model.
