Well, this isn't a BeOS advocacy list, but the manner in which the engineers
did it is quite exceptional and Linux folks should hold judgement until
they see it in action on slow 601 PPC chip.
The BeOS scheduler is quite fast and so is the file system.
X Windows is *NOT* the entire GUI universe and that should be respected.
Same goes for the Linux kernel as the FreeBSD folks will attest.
