Ok, we won't ;-) - not quite: the TCP/IP stack was borrowed by M$, but I 
was trying to be specific about (open-source) kernel cores here. That's 
what Darwin is (to MacOSX), and it could well be one of the most 
advanced available to consumers. It will be interesting to see some 
performance benchmarks, and whether Linus's view of microkernels has 
been disproved. Certainly Mac looks like the simplest possible 
recommendation for (affluent) newbies now.

I once tried a search to discover whether msdos.sys or io.sys was the M$ 
kernel, unsuccessfully. Someone here will know; Wesley?! :-)
