Clarifying edit: Touch is great if you are holding the device in your hands, of course, like an iPad. But once you are using a keyboard and Surface's kickstand and trying to run Windows apps, which is the use case we're discussing here, you'll need a mouse or a trackpad, just like you do to run Windows on any other device. Windows apps are not touch friendly and that didn't magically change just because Ballmer is trying to enter the market that he publicly mocked in 2007 (iPhone) and 2010 (iPad).
