> Most likely scenario in my mind: Most people stay on older versions of Windows for quite some time to come Remember that Vista, a major flop, was the fastest selling version of Windows at one point. The enterprise skipped Vista but consumers did not because most consumers upgrade their OS when they upgrade their computers. > those who do use Windows 8 prefer to stick with the Windows interface they've used for the past 16 years. I assume you mean they will spend most of their time in Desktop. That's fine, but that's still a potential sale. The Metro start screen can't be avoided; the old start menu doesn't exist any more. So the "Windows Store" logo will be staring at users every time they go to launch an app (whether Metro or desktop). You can do the numbers and gather that there are going to be a lot of people at least exploring the Store at some point.
