There already is
Problem is, after June you will not be able to get updates or Ulimate extras. Get freindly with some MS top dogs, and you get fully legal Vista for nawt
I made a few contacts with a m8 who delt with Mr BIG himself at QE2 conference . Not only did he arrange to get Vista for nawt, but he got base units ordered with it Pre-installed
Walked out of there with XP discs, Visual studio Pro 2005, Server 2003 and a stack of other MS goodies . Guess it's just a case of who ya know
