"Just look at Vista and Windows 7, could someone please explain why the OS
went from 4GB in Win Xp to 11GB in Vista and Win 7 ??? without gaining and
new usability. Sure it's got nifty graphics, but 7GB worth ?
Really can anybody explain where the 7Gb went ?"

I know a large part of that is actually in a extracted set of cabs so
they don't have to "get the CD" all the time for driver installs and
updates ect or feature adds.
