In my case, my machine certainly has the 3D hardware required to actually use Netbook Edition. However, restricted nVidia drivers are required to do so, and not being able to use the default Desktop Edition UI to get those installed makes for a difficult experience. I would agree something needs to be done so the user gets some sort of prompt or fallback so these sorts of things can be taken care of quickly.
