The reviews so far say windows 8 is a solid OS, BUT they almost all trash the new UI in some way for its inability to open more than one program, or window at a time. Which was the cornerstone of Windows to begin with. Plus its vague access of programs we could easily access with windows 7. Yea that is the risk when you change "everything".
I am sorry, but i need to be able to surf the web, have XSI, Photoshop, SoTSE dev, and beyond compare open at the same time. Also to switch seamlessly between them, or have multiple windows open on my screen. It seems they made Windows 8 for the people that have ADD, and that can't multitask. In other words they over-simplified it. In doing so they made things much more complicated.
