The hardware that RISC OS runs on is boring. It is slow and out of date. A port to a different architecture (x86) would open up access to faster, cheaper, hardware and renew interest in developing support for much needed features like DVD playback.
The point is if it becomes apparent to VirtualAcorn that enough people won't buy the product due to the copy protection maybe they will tone it down a bit.
When activating my legal copy of Windows XP I've never had to phone Microsoft even when I've changed hardware around a lot. Also it is unlikely that
Microsoft will disappear overnight leaving me with no way to activate the software. There is also the point I can defer activation to a time that suits me.
I don't think the same can be said of VirtualAcorn's products.
