"Virualisation....relatively little...performance hit": not according to the tests run by T.O.M.S. in the latest Archive, where the performance of various David Pilling ports of RO apps to Windows (Trace, DPScan, OvationPro) was compared to the RO apps running under emulation. The ported apps running natively under Windows were 5-7x faster than under RO emulation! Now it may well be that further development of VRPC will improve this ratio, but clearly ATM there is a considerable overhead when running on top of Windows. To put it another way, a RO app will run under emulation on a 3Ghz+ x86 processor at roughly the same speed as on an Iyonix with its 0.6Ghz ARM processor.

As to where we go from here, I suspect that emulation and x86 improvements (including dual-core and 64-bit chips) will outstrip the speed improvements in suitable ARM chips. I'd love to be proved wrong, and I'd love to see Iyonix 2 with a 1Ghz+ ARM chip, full graphics card acceleration and modernised filing system to replace the Iyo on which I'm typing this.
