In my opinion the current RISC OS logo, the cogwheel, is fine. It's the ROL logo (which incidentally has probably been done using Draw by a non-designer in a few minutes) and their particular usage of the riscos.com domain that annoys me, personally. If they can't properly keep it up-to-date and an accurate resource, they should pass it on to someone who can.
The 256 colour Acorn-palette puzzle pieces, the seemingly random structure of dated or even inaccurate information, stone-age webdesign. Think about the RO4.02 advertisement dating back to 1999 still prominently displayed on the front page while no mention is made about the current ROSix, dated information regarding Select among other things - utterly unprofessional and counter-productive to their supposed aims. I'm sure there are some people around willing to do a site overhaul for ROL, if only to get rid of the current thing. ROL just needs to ask. The OS desktop cosmetics is obviously a bigger job and probably require professional dedication from a true designer, such as Richard Hallas. But, in all fairness, it seems ROL can just about sustain its own existence, barely any fundemental OS development and can hardly financially justify a cosmetic overhaul of the RO desktop... I'd say nowadays getting a Select subscription is mostly about putting food on PM's table.
