You see I'm kinda moving towards the 4GB model rather than the 250GB due to me being poor.And I have no intention of doing Xbox Live due to money requirements,I have no intention of installing games either and their's only few games I'm wanting for the 360 what I mean by few is less than 8 So with that being said is 4GB enough just for updates and Game Saves of about 5 games?
As long as you don't get Bad Company 2, it will be enough. Updates for that game are generally between 1GB and 2GB.
I have no idea of the size of the game saves, but it should be plenty. For updates its another history though, some games may have sizeable updates, so in the end you will need to delete update from other games for it. Well, I use a 60gb HD Xbox, even though for me is more than enough.... isn't 4GB to small? Thats kinda less than a pen drive nowadays.
You could just grab an 8 GB flash drive and use that as extra storage if you need it. Could go a little bigger or smaller if you choose.
