Microsoft has confirmed that all versions of Vista will be included on one DVD. The feature, called Windows Anytime Upgrade, is intended to enable users to more readily upgrade to a “better” version of the OS. Users will be able to move up by simply purchasing a new product key.
This is probably a pretty good idea. Not only does it cutdown on the overhead of packaging, it will likely increase impulsive OS upgrades. I imagine people will be drastically more inclined to upgrade their OS on a whim if it’s already sitting on their desk.
Edit: Interesting thoughts in comments from webonics and Artega that I hadn’t even considered. They’ve suggested that perhaps MS is essentially encouraging hackers to pirate Vista as part of a diabolical scheme to increase market share and bury Apple once and for all. Yes, yes that must be it. What do the rest of you think? (conspiracy theories encouraged)
