Wow, I see as usual most of you are missing the point of this upgrade entirely. Metro isn't going to be a big deal. The only reason people are complaining is because most people are always complaining about anything they aren't used to. The main thing most users should be considering is that this new OS has improved speed in almost every category compared to Win 7 and XP. For those people who have a hard time understanding this, that means just about everything you do on your computer everyday will go faster than it does now. Speed tests have proven this. But the best part is that all of this comes at only $40. That's a pretty sick deal for a speed boost across the board.
People can get used to anything over time. I can get used to eating cold pizza and drinking warm beer. But if I have a choice I want hot pizza and cold beer. Windows 7 Ultimate was new when it came out and I never had to "get used to it".
The reason everything goes faster on Windows 8 is because cellphones and tablets were added to the equation when calculating what the final product would be like. "Speed" isn't the holy grail of how one chooses which operating system to use. It's a factor to be considered amoung many, many others. The speed of Windows 7 on my computer is just fine. Stripping out complex UI themes for simplistic tiles and telling me its faster isn't an incentive to upgrade to Windows 8. Of course its faster. Because instead of attempting to harness the full power of a desktop they started with the power of cellphones/tablets and used that as the common base when making software design choices. Saying everybody should upgrade to 'Windows 8' because of a speed boost is ludicrous. Releasing the same functionality at an improved speed would be something to talk about. Designing an operating system with cellphones/tablets in mind and then adapting it to the desktop and then telling everybody its faster than Windows 7 is comparing Apples to Oranges.
Yeah, $40 is a pretty sick deal. That's not a bad price to convert my desktop to a cellphone/tablet OS.

There is one huge thing which many missed with regard to new UI/kernel unification + optimization, I.e. MS is drawing up a course for 'unified' application development for mobile+desktop platforms. Skipping the merits or demirts of it, the logic seems solid IMHO, and if they succeed in it, it will stump both Google and Apple, putting them on-course to continue to dominate computer industry for many more years. The question is, can they pull it off and get programers on-board?
Actually, I don't think alot of people are missing what Microsoft is attempting to do at all. I think almost everybody who is unhappy with the new Windows 8 OS sees exactly what Microsoft is attempting to do. I think the unified application development of desktop+mobile platforms is the most obvious and glaring reason for most people's complaints about Windows 8. It's an assumption that one UI can be designed that will work equally well across all devices. So, whether or not you using a 27" desktop monitor or a 4.3" cellphone screen you will be using the same interface. I don't how your brain works but, on the contrary, this doesn't seem logical to me at all. It seems completely delusional. And since cellphones and tablets lack the raw power a desktop CPU the "unified" operating system gets designed around the lowest common denominator so that no child gets left behind.
