It seems that Vista's new GUI, Aero, won't play for free. Windows will "confirm" that you own your copy of Vista—we all know who hacker proof that was for XP— before it shows you all the goods—translucent windows, fancy buttons, animations—and if you don't pay up, it will dump you back into Windows 2000 mode... or worse.
Like one of those Go Go dancers behind a metal blast shield, Vista is coy and sexy only to those who insert 50 cents. So, if you want a unique GUI experience, please don't hack Vista—or download a version that's already been hacked. Instead, you should pony up for an iMac and BootCamp and enjoy all the animated windows you can stand.
