With respect druck, please don't try and compare your own results with a self-built/off-the-shelf PC and those of a RISCube. I know you think you can, but just to give an example, a chap brought in a fairly high end core2duo system for me to work on 2 weeks ago. It ran about a quarter of the speed of a similar RISCube due to the selection of parts and configuration. Obviously it will depend on the program, and I don't know the insides of photodesk, but I've had computational tests running over 5 times faster than an Iyonix. Clearly it will depend on exactly what the software is doing (just as an Iyonix varies wildly), but it is perfectly possible. Anyway, I know that for you (and many others) only a native ARM cpu is acceptable, and that's cool, but for other people, it is still possible to stick with RISC OS and have high performance. Take the guy who received his RISCube this week - his most-used computational operation dropped from 3minutes (RiscPC) to 3 seconds. He has his machine configrued so he never needs to look at Windows.
