VMS supports a graphical user interface too. Instruction sets are
a property of hardware. Flexibility is important... 

BUT the main reason unix is preferred over VMS is that it is
not the proprietary product of a single vendor, like VMS. 
When unix was developed at Bell Labs, the phone company couldn't
sell software, so they basically gave unix to universities.
Hence unix is now widespread, and runs on everything from PC's to
Crays. I *do* *not* claim that unix is better than VMS... I have used
VMS, and it has certain advantages. Someone I know at digital
who sneers at unix admits that they should have given VMS away...
...if they had,  maybe it would be the OS of choice today and not
unix. If you stay with VMS, you are at the mercy of a company that
may become bankrupt in the next few years.

They are *very* useful once you understand them.
The level of the average mol. bio. user will have to improve
over the next few decades. It is simple as that. I still remember
when the average bio. lab needed to know nothing about 
cloning methodology---no longer true! Using the full power
of unix is like *not* buying all your enzymes in  little kits...
...the best labs usually don't, because they understand the
technology best.

That contempt is misplaced. Ask them if they can write an Air Defense
system in Unix :-) (VMS does realtime, unix doesn't). Nevertheless,
you could be a victim of the market... be warned!
