>"Emulators are selling WindowsXP to Acorn users..."
In my experience, it's more like "RISC OS users are being forced on to WindowsXP, and emulators allow them to keep supporting RISC OS".
My father is being forced to move to a PC by his work for 'compatibility reasons' (i.e. Easiwriter's Word facilities aren't good enough and there's real way he can handle Excel on an Risc PC); he has 14 years' worth of Acorn files to keep and 14 years' of experience of RISC OS computers. He's far more likely to be able to persuade them to buy him VRPC than an IYONIX (at practically ten times the price).
Of course it's sad that he has to move at all, but I don't think in this case an emulator is making it any worse.
