"Castle and ROL need to communicate the advantages more clearly."
This is the key. Everytime I talk to normal people (=not computer geeks) they know about Win, they know about Mac, they even know about Linux (ofcourse they have not any clue about what they are), but NONE of them have ever heard about RISCOS.
W/O advertising there's no business. RISCOS web site looks crap, there's no advertising in computer mags or via google ads. In a fast computer world like the one we're living in, you've no hopes if you don't move faster & faster.
Today who hates Win, wanna MAC, and who wanna be "intimate" with the machine wants Linux. The fun is that RISCOS can be as much MAC-like or as much LINUX-like as one wants, as it's simpler than mac and deeper than linux.
