Not sure if anyone is still reading replies to this thread, but here's my oar put in...
I'd dearly love to be running my RISC OS apps on this Linux laptop. Can't vouch for everyone, but I certainly stick with RISC OS for the applications.
Of the examples given, Ovation Pro does run under WINE, but using it is another matter, I get all manner of random crashes (less so with latest cvs version, but still there) and not worked out how to get it to print yet. But StrongEd kicks ass compared to the current editor I use (kate) and I really really want StrongEd!! TechWriter blows KWord out of the water (and fwiw, I much prefer it to OpenOffice.org also). Artworks leaves InkScape standing and don't even get me started on the bloody mess that OvationPro leaves in a celebrity deathmatch with Scribus. Please please consider porting at least some of these to Linux, for most I'd be more than willing to cough up for a 2nd license (and I'm a stingy git!). I suppose VA for Linux would alleviate some of my probs (hint hint, please please, beg beg!).
On a more serious note, surely there is substantial revenue opportunities for many RISC OS under linux - not that I've been using it that long, but there does seem to be many fewer 'dominant' apps and perhaps RISC OS ports would stand a damn good chance with fewer 'big-boys' around.
PS. God do I dislike laptop keyboards!!! 16 time I clipped the touch pad and sent the window scrolling - just thought I'd mention it (make it 17 times now!) GRRR!
