It's amazing how much Sony and MS got right for each of their consoles, and how much each of them screwed up on different points.

This is one of Microsoft's most dismal failures on the 360: they should never have released a version without a hard drive.

It makes a nightmare for the developers (who either can't rely on the thing being there to make use of it, or have to do shit like this that screws their customers) and the users as well, many of whom aren't going to realize until it's too late that some games just won't work completely on the console they were allegedly made for.
