The question isn't whether emulators work well or not, it's whether their presence will kill RISC OS in the long term.
Apple survives because of the profit they make on their hardware, RISC OS needs the same. Also Apple couldn't get fast enough CPUs, so they sell dual processor machines, we need RISC OS to be updated to support that otherwise we can't compete.
Obviously some people need the extra features in apps not provided by RISC OS software, but the majority don't, and benefit from the superior GUI etc of RISC OS. We need to compete on speed and ease of getting the job done, not raw power and features, because we can't there.
If you save 1hr per day because you work on RISC OS at 5ukps/hour your Iyonix has paid for itself in half a year.
Now to use VRPC you also need to know about Windows, windowsupdate, firewalls, antivirus, defragmenting, services, and how to fix it when it goes wrong. And when something's not working you need to know whether it's the hardware, windows, VRPC, RISC OS or the app that's the problem. The potential problems at least doubled, so the time to fix them quadrupled.
VRPC has the same obvious price advantage over Iyonix as Windows does, and many of the same longer term disadvantages. And you're not contributing to the long term future of RISC OS on ARM machines.
If you think that VRPC won't contribute to the decline of RISC OS on ARM, or want to be using one of the many thriving OSes that only exist in emulation, then go ahead. If you don't really use RISC OS much anymore, and just like VRPC because it's cheap for messing about with why are you even here?
