Engadget reports Microsoft might developed an instant-on Windows operating system. It's not sure if Microsoft will develop such an operating system but they're definitely thinking about it:
A recent Microsoft survey sent out to select users has us wondering what on Earth the mega-corp is planning to do next, and judging by the looks of things, it has everything to do with Instant On. We've seen a number of these lightning-fast boot applications, with the most recent being ASUS' Splashtop OS and the iteration loaded onto Dell's freshest Latitudes. The survey makes mention that the "Instant On experience is different from 'Full Windows' because it limits what activities you can do and what applications you have access to." The survey also asks about which applications would be most important to have quick access to, and it very plainly states that in this "scenario," your PC would "be usable in eight seconds."
