I did notice that the HURD folks blamed most of their delays (and thus the rise
of Linux) on MACH.

I'd think that would be a horrible disadvantage on the PC platform. Folks are
going to want to be able to boot off of SCSSI devices, CDROM drives, Floppies,
ZIP disks, LS-120's, PCMCIA drives, firewire drives, and whatever else they may
invent next week. Its OK to not support all that stuff at first, but it should
be doable.
