Also Linux has virtual consoles... :-) plus free X11 if you will install
it.
About I/O speed, let me throw my $0.02.
I have tried both Coherent and Linux.
Under Coherent, my disk is slooooow, about 30 Kb/s. With some trickery
(hackering file-system parameter), I can speed up to 100 Kb/s.
Under Linux, without trickery, run about 300/400 Kb/s.
These number are from iozone.
On the "human" side, Linux is faster, commands come up immediately.
I've found Coherent 4.0 is also slower, for the human eye, than Coherent
3.2.
Consider that my system is one of the slowest Coherent and Linux support!
