I completely hated Windows 8 when I first used it, and have resisted moving to it as my main OS so far, but that's about to change. I had installed on a VM on my machine just so I could do some compatibility testing on my machine, and after using it for a while I'm completely sold. It was crazy confusing at first and I didn't like the way it looked at all, but I can see now the reason for it. It's CRAZY fast. I generally have about 6 apps running all the time, mostly development and database tools, and even in a VM I noticed that they were running significantly faster than the same apps running on my host Win 7 machine. I think a lot of that has to do with the new minimalist UI. No more wasted CPU cycles on making everything shiny/transparent. It's just sleek and streamlined. I'm still not crazy about the color schemes and new ALL CAPS menu system, but I guess it's ok. The most important thing I've learned is that if you plan to run Win 8 on a PC/laptop, you need to know your keyboard shortcuts. All the old shortcuts are still there (Alt + F4 to close an app/shut down, Win = Start Menu, Win+D = Desktop, Win + Arrow = Move window to different monitor), but a lot of the UI buttons for those have been either removed or moved around. So long as your comfortable w/ using the keyboard to navigate the UI, I don't think you'll have any problems with. The problem comes in if you rely heavily on the mouse to get around. Win 8 was definitely designed w/ the tablet PC in mind, so many of the navigation features employ the touch screen, gestures, and special buttons that those types of devices have. For those using it on a PC, though, I think the thought was that the keyboard is still the primary UI device.
