I think the easiest way to minimize confusion would be to market ARM-based Windows machines as “Metro only”. Intel gets classic Windows and Metro apps, ARM gets Metro. I don't think this would be that much less confusing for lay users. I would imagine MS will rely on pushing 3rd party software through their App Store, and only exposing compatible software. I imagine this will work better to minimize end-user confusion and to enforce developers doing real ports of their applications instead of just recompiling.
