simo: I think the brief answer is that RISC OS isn't going to hit mainstream any time soon - it missed that particular boat when Win 95 was launched. It still has a lot to do technically to catch up with even some of the other 'niche' OSes. However, if we assume that things aren't 'mainstream or die', which I think we've now got lots of evidence that it isn't (Linux growth, Mac OS growth etc), then RISC OS is in a strong position. For desktop performance-per-Watt, the A9 is almost certainly unchallenged in its field. The RISC OS GUI has always been a strength, and as you pointed out, long-lacking developments /are/ coming to the fore at a time when IMHO software innovation has been slowing elsewhere. The growth of open standards is also highly beneficial to the platform to allow us to compete on a level playing field.
