How big of a file is Windows Vista Business full?

[preslove]

My MSDNAA account says that the ISO file for Vista Business is 2.3 gigs, but I've heard that it is six. I don't see an ISO ballooning to 3x the original size during the burn. Is the MSDNAA site lying to me?

The Vista RTM ISO I downloaded from MSDN for work was 2.3 GB not 6.

Correct. I just installed it today, the install took 7GB! What the hell are they loading on there??
