Reply to Richard Hallas,
I should have clarified my statements. My major (MAJOR!) beef is with the ROL logo, it's just unspeakably terrible. The cog logo, while I don't especially like it, is competent, and I don't have any major issues with it. The Iyonix blue blob is not good, if only because it means absolutely nothing, and is very unmemorable.
Whatever we think about any of these logos, they've been around a while, and maybe could do with a 'refresh', I just think that a really fresh, new logo for RISC OS, and a few new nice icons in the OS could give the OS and the community as a whole a bit of a boost.
I think a nice logo, website, and all round appearance is quite inspiring, to use the example of Haiku, as I have elsewhere: Haiku is in beta, it's not a whole lot of use in the real world, but I think their lovely website, logo, and appearance of the desktop makes people think that it has a good future ahead of it, and makes people glad to be a part of it. RISC OS, on balance, is probably more useful in the real world than Haiku, but the impression you get from all the websites about it is that it's ancient, ugly, and all round a bit crap.
ROOL, I think, realise this, and their website is clean and pleasant. iyonix.com is alright, but a nice logo would make a big difference. ROL's website is beyond saving I think and needs redesigning from the ground up.
Lot's of companies would refresh their branding after 5 or so years, maybe we should too.
