Which greater than 90% of people will use without being aware of the consequences, so in effect, it is a weakened UAC. Windows 7 will still be a step up in security from XP though, as it will no longer be necessary to be logged in as an administrator to do anything useful.
Its still a UI overhaul not a change to the core OS. This, by the way, should also be applied to Vista as a matter of course, but that will never happen. I expect to get a little more than a year or two out of my OS before I feel compelled to upgrade. Anything else is just MS squeezing me for money.
I see no reason to fork over $200 to MS to upgrade my Vista premium for OS fixes that should have been done anyway.
30 Windows?? You probably spend more time switching windows than I do on my computer. Call me old fashioned, but I like to do one thing at a time, maybe two. Task switching has a HUGE overhead.
I might if I can get the $39 student version. On the other hand, for free I can also try out Ubuntu with a UI.
The most compelling reason I had to stay with Windows was for an HTPC, which needs HDCP support. For playing music, web browsing and the basic home stuff, the OS flavour is irrelevant.
