Pros of Iyonix over a RiscPC
Very high screen resolutions without compromising speed.
Soundcard as standard supports audio/mic in now has the !AudioIn application for sampling from any on board sound source.
Built in USB support.
It is available.
Support for many older applications (some which will not run on an SARPC) via AemulorPro.
Iyonix will take cheap PCI cards for example allowing you to watch TV on your computer for less than the price a new TV.
Flash ROMs allow immediate user update of operating system.
Standard Iyonix tower can take more drives/devices than a single slice RiscPC.
Iyonix podule bus is faster than that of a RiscPC.
You can build an Iyonix motherboard into any number of funky PC cases.
Excellent support group.
The advantages of the Iyonix are such that my StrongARM RiscPC with 8MB Viewfinder now only gets switched on to use the SCSI scanner.
