I agree that it is smart of Microsoft. Most people using a computer, that I've seen, know so little about what it does, and how to prevent trojans, spyware, worms, etc. If you can't turn off the UAC, that's for a GOOD reason. If you can, then you are likely knowledgable enough to stay away from the trojans, spyware, etc.
Most people who don't like Windows Vista are either Mac lovers claiming Microsoft steals everything (Which I think is bull**** because they originally stole Xerox's GUI, and they wouldn't even be Mac lovers if it weren't for Microsoft anyhow... Investing over a million something dollars into Apple). Excuse me, but this could turn into a long rant, so if you haven't done so already, make some popcorn. Okay, next I have seen that a lot of times some one is using the other OS because of either A) They hate MS because for no real reason, or hate MS for their ethics (Which, btw, is stupid because despite their ethics, they still manage to donate a ton of money to charities, and in fact, donate more money than anyone else, or so I've heard), and/or B) They want to be "Uber l33t". And your OS doesn't make you "Uber l33t", you're knowledge on it, and programming abilities does, IMO. Also, Mac and Linux users claim to be the most secure OSs in the world because they have little to no spyware... Well, if 80% of the world used Mac or Linux, don't you think there would be more trojans, spyware, and the such on that? If not, your head is way to far up your a**.
Quite honestly, I am well aware of what I have ranted about is uncalled for, but to prevent more threads coming up about such a thing, I'm posting this anyways. I use Windows Vista and am quite happy with it. The bugs where minimal, and most of them were fixed! Windows Aero is amazingly fast, and the Basic/Classic themes even faster! It's a new OS, of course not all the hardware is going to be supported! They REWROTE EVERYTHING in the OS, claims MaximumPC (A very trustworthy PC magazine here in America). It gets the job done, it's popular, and a good majority of programmers use Windows, those are only "surface scratching" reasons why I like Windows, there are a ton more, which I would be happy to post if any one is interested.
