drjones69: "As to why would someone want a RISC OS emulator on Linux, no software worth using you say? Allow to me to suggest a couple of apps and perhaps you can demonstrate what I could use under linux instead..."
Well, let's see. Ovation Pro is an interesting case because the Scribus team seem to be regularly scoring own goals, messing around with the interface (going back to ancient Quark/Pagemaker-style story editing), and generally not coming through very quickly. Meanwhile, Inkscape (and other tools) are coming along to at least rival ArtWorks; Photodesk is arguably surpassed by a bunch of Linux applications; TechWriter may be nice, but my sources suggest that it isn't up to it for certain kinds of documents and that the now-mature LyX is a much better choice.
As for text editing, I don't think anything on RISC OS touches the range of tools available on UNIX-like systems. Draw was a classic application that provided a good compromise between ease-of-use and features, and I do miss it on Linux, but then stuff like OpenOffice's drawing application can be pretty good replacements.
But there are a number of differences between the RISC OS apps and those on Linux: most of the RISC OS ones are commercial, and the underlying GUI libraries and frameworks on X11-based platforms are moving forward all the time. Yes, RISC OS had good solutions for some of the problems only now being standardised on other platforms, but that's another big difference: widespread, free (in all senses) standardisation. None of that makes it a great idea to run old apps in an emulator forever. Perhaps MW and DP should join forces after all...
