They messed up Vista so bad that the DoD refuses to let it on their computers and I do not think they have learned anything from the experience.
The Stalinistic DRM for Vista will probably get even worse for the retail/OEM versions of 7 and I have heard from some developers it actually disables your high def audio even for video that you have made and rendered yourself.
Their quest to squeeze every penny of licensing fees and make us pay for the content of everything, whether it should be paid for or not make their software bloated and totally unfriendly (remember that liberals would kill you for a buck but scorn you if you want to earn a buck yourself).
I finally built three new computers for home and loaded them with XP Pro 64bit. While there is some software that does not work on the 64bit XP I like the added security and how FAST it is with 3.2 Gig processors and 16Gig RAM. Also get to use the High Def audio and video at my leisure.
There are rumors going around the internet that are absolutely false. Vista and Win7 do have DRM, but it's only on specific DRM'd files and discs.
