I'm an absolute noob when it comes to the world of Xbox and need a bit of advice. I'm planning on buying a console in the not-too-distant future and, after some research online, I'm somewhat confused. Some reviews say that the 4GB is plenty of space for a casual gamer (that's me), while other reviews say that even for a casual gamer the 4GB fills up mighty quick and I should get the 250GB. I'm not a huge gamer (maybe an hour a day, if that), I don't necessarily plan on playing anything live nor will I be downloading movies/music/etc. In fact I'm really only buying the system in order to play Oblivion, the forthcoming Skyrim, and maybe Fable. So then, should I buy the 4GB or spring for the 250? The 4GB seems like the glaringly obvious answer to me, but I'd hate to buy it only to realize I don't have enough space to save/play games...any advice would be greatly appreciated!
