A bigger HDD doesn't matter at all, you can always install a bigger one (wish you could do the same with the x360, I wouldn't be still debating whether to get the Elite model or not :/ ), now the backwards compatibility, on the other hand... I'm glad I rushed my decision on getting the 60BG model with BC even when there was no game I really wanted to play.

Also, Darth I edited your post, that site contains warez indirectly, if you want to link us to it, please copy and paste the new as I did.
