In most operating systems, too much time is spent selecting, moving, resizing, opening, and closing windows. While windows provide access to the content and applications we want, the overhead they carry with them is high. This leads to time spent managing windows instead of getting things done and ultimately unhappy users.
So it's no wonder that new operating system designs all try to tackle the window problem. The following video is a compilation of new interface design solutions for application access in Apple's Snow Leopard, Google's Chrome OS, the litl Web book, Microsoft's Windows 7, and the conceptual 10/GUI from R. Clayton Miller. Enjoy.
