Is the Windows Vista hype machine rumbling alive this early? The operating system isn't expected to debut until November or December and yet PCWorld.com delivers a breathless writeup of "10 reasons to buy Windows Vista."

The author divines nine reasons after playing around with a very early test version of Vista: Good security, improved browser, it looks pretty, better desktop search, better updating, more media functionality, parental controls, a better backup program and collaboration ability.

He added a 10th reason even though he has yet to actually see it: faster setup times.

Perhaps the reviews can wait until a more complete version exists?
