Um, I didnt say it was like modern VM unix, only that its origin is unix-based.

This would be fine, except that many of the "obvious" advantages are horse-nonsense (like the moving parts BS). The issue is that unless your talking very high density or very high end, the "advantages" are mostly propaganda. your (ridiculous) allusion to the "Sun Sparc" is a clear indication that you just dont get it. The advantages of a PC are the high power/ low cost ratio, modularity and availablilty of low cost subsystems, and mass production cost attributes of virtually all componants, as well as the wide variety and functionality of inexpensive software, virtually none of which are attributes of the Sun Sparc. db
