Here's an interesting tidbit: Microsoft says that Windows Vista will check to make sure users have properly purchased the software before allowing them to use the flashy, much-hyped Aero interface. How they intend to do this remains a mystery, though CNet hints that it will be through the Microsoft's Genuine Advantage program. Considering that every anti-piracy measure put in place by Microsoft has been defeated by pirates within weeks, if not hours, I can't imagine Microsoft actually hopes that this is going to be effective in deterring pirates. Anybody who knows how to use BitTorrent will be able to have a fully-working Vista install, Aero included, within days of its release, and Microsoft knows that, so I'm not sure what this little bout of anti-piracy hand-waving is all about.
