if you port MOS to x86, then it would just be AROS. I guess its what makes it unique is that its still clinging to PPC architecture.
This damn EFIKA board w/MOS2 is just awesome though. Best $99 I've ever spent. Once I come back from Cancun in about 2 weeks I'll look at registering MOS. Too bad I missed the cheaper price deadline...oh well.. its still worth it.
