Thanks for an interesting and informative article. The reference to the Prism project was particularly interesting, and frustrating in equal measure. I have used RISC OS as my main home computing platform for the last fourteen years, and although like everyone else I suffer from the well-known browser and multimedia shortcomings, thanks to the efforts of dedicated developers such as David Pilling, Martin Wuerthner, Dave Higton, Anton Reiser, Rob Davison and many others, the ability of RO to handle daily computing tasks and interface with other platforms has never been better or more complete IMO than it is now. If the same level of dedication can be applied to development of the OS itself, much can be accomplished. As to the ARM platform, the impetus to greater speed and power is clear, driven by ever more sophisticated hand-helds. We should not forget either that there must be many more ARM chips in daily use than any other platform, x86 included.
