I think this isn't necessarily about using a tablet or phone interface on the desktop, it's about using either one depending on what peripherals you are using. One configuration is a separate OS instance per device, but a more interesting configuration is basically a phone that you can hook up to a monitor, keyboard and mouse. So basically you get a mobile interface in one mode, and a desktop interface in another. I'd much rather have a single small device i can lug around everywhere I go instead of separate devices for home, office and mobile. Given how quickly cpu speeds are progressing on mobile devices and the prevalence of cloud hosted applications, this could be a possibility sooner rather than later.. And regardless of that, this is about having a single application platform for all the form factors. This video shows a tablet interface, I don't think they will force you to use it on the desktop, at least as shown here. I think the point was the same apps can run everywhere.
