If I bought the Arcade, can it be upgraded later with more disk space, or can I use some sort of external memory/storage?
All the more expensive Xbox's have over the cheaper ones is a bigger hard disk drive,which you can buy and install at a later date or separately.
It kind of already is external in that it just slots onto the side (the hdd) but I think it has to be a Microsoft one.
So I would personally go for the cheaper Xbox,I play most of my games online and from the disk and I have no problems.Installing a game is nice in that sometimes it does improve the load speeds (not by that much though) and you have a copy of the game in case the cd every gets damaged.
