This would be a great option for the many individuals who use their computers for nothing but productivity and browsing. You wouldn't need to buy Office and a new computer up front, and theoretically you can stay up-to-date without buying an entirely new laptop.

You'd just need to buy a lightweight device (similar to a Chromebook) with a screen. Of course they don't even support Chrome right now (IE and FF only), but the idea would be solid for almost anyone who doesn't game or need low-latency computing.
