I also have something more powerful, flexible, and upgradable than my RPC - that it runs RISC OS natively rather than emulated is of no consequence
As I said, I'd have to be pretty desperate to pay for a Windows machine. If I ever get desperate enough, that machine is more than likely to be a portable running VRPC (although I'd gladly take a Linux/VRPC portable any day).
It's the block mentality of "VRPC is here, I'll hopefully never need to use my genuine hardware again" that will eventually kill the market, in my opinion.
As for me "not understanding Windows", perhaps I should have stressed that, compared to how I use and enjoy using my Iyonix, the Windows machines seem little more than toys to me. Far from it that I don't understand them - to use your analogy, the gas fitter is quite sufficiently equipped to fix your average boiler, but he finds more joy in spending time tinkering with his cold-fusion reactor.
