No, it would be useful if they ditched the limit altogether so I can store stuff on a 500 GB or 1 TB hard drive.
But then how would they sell their hard drives?
They wouldn't need to sell their drives at all if they would put the emulator for the XBox Originals up on the marketplace as a download, make people who actually want it pay a reasonable price for it and call it a day.
Just their free game giveaways are going to come close to filling my 320GB HDD, I've already had to uninstall 95% of my games to make room for the free stuff.
