I bought the 360 gb with intention than 4 version. As currently everything is contaminated with piano lacquer felt this variant in handy, for this reason I have omitted the 250GB variant! The biggest shortcoming is clearly the undersized memory, 4 Gb you really will not get far! At the moment the only option is to a 16GB USB stick to buy if you need more storage! (External hard drives can only be to a memory size of 16 GB use what I feel as a rip-off in order to have recourse to expensive Microsoft Accessories must) from the drive will be 1 GB for the settings as Memory Unit flutes so we still have 15 Gb! The internal flash memory is only otherwise has to serve something to 3Gb since 1 Gb or furnishing! So you have together 18GB memory which is enough for now! I have the 360 pending exclusive titles such as Halo Reach or Gears of War 3 risen. For this purpose and 18 Gb memory all! If you're looking piano lacquer and much Gb should definitely resort to 250iger variant! IMPORTANT: I can not agree with the previous speaker for the rear USB inputs can be used properly for USB sticks!
