This to me raises an interesting question. Does it actually matter what hardware RISC OS is running on?
To me it doesn't. As long as it works and it works well then I don't care what it is running on. And to be honest if you can run it side by side with Windows then I would consider it to be a very big advantage.
The reality of the situation is that I cannot see myself forking out over a grand for RISC OS specific kit, when for the same price I could get a much more powerful PC that could do a whole lot more. I also expect I am not the only one in this situation.
If it is possible to run a working version of RISC OS at a decent speed on a PC, then at least this way I would be able to continue supporting the development of RISC OS in some manner, rather than not at all.
