This statement is very subjective.  What unix box are you running?

SunOS and the MIT X11R4 server on a SparcStation seems pretty peppy to
me.  With MacOS windowing, anything with less guts than a Mac II makes
me impatient.  And Unix/X deal much more gracefully with multiple
concurrent tasks.  (Something which weighs heavily on my mind while the
watch hands rotate...)

Again, what unix machine?

If you want REAL speed on bootup, try a Timex/Sinclair 1000.  It's
up and running in less than a second!  Why, you could turn it on
and off all day long!  :-)

When you have a unix box on a network, you usually DON'T turn it off.
It runs scheduled operations at night, and may have to deal with
network connections at any hour.  What does bootup speed matter when
you boot once a month?

>Is connectivity all that good?

Yes, regardless of whether you're on MacOS or Unix.  Try out NCSA
Telnet, HyperFTP, HyperFinger, etc. on a Mac sometime.  (All require
MacTCP first, though, from Apple.)

[Warning: next paragraph contains heavy sarcasm.]

X virus?  Kinda makes you wonder why it hasn't happened yet, eh?  What
with all those Mac and PC viruses (viri?), and I haven't YET seen a
Unix "virus".  Perhaps Unix isn't as susceptible to viruses as
single-user, no-memory-protection, no-file-protection machines are...

"What about the internet virus?" you say.  It wasn't a virus, it was a
worm.  Possibly nitpicking.  What IS important, though, was that it
propagated though HOLES in Unix security (many of which were well
known and easily fixed).  PC and Mac viruses propagate through the
complete LACK of security.

On the other hand, look what networks (the internet, anyway) get you:
  Instant access to terabytes of software, databases, images, sounds.
  Email to other sites delivered in minutes (sometimes seconds).
  Real-time communication with other folks on the net.
  News (USENET, seperate from internet access).

>Why do I need the sysop rooting around in my files?

Maybe you need an honest sysop.  Or, if extremely paranoid, a quick
lesson in how to use "crypt".

Of course, every janitor in the building has a key to YOUR office, and
can turn on your Mac or PC and copy files all they like.  Unless you
invest in some kind of non-standard third-party security stick-on.

Really?  I thought you said they wanted to use word processors and
spreadsheets.

Hiring a sysop is not buying a "Big Brother".  Sysops take care of
nitty-gritties - dumps, installing software, fixing hardware, etc.
There are Mac sysops, as well as Unix ones.  But the expertise level
must be higher for Unix.

It sounds like you've never really used mail or ftp.  Try transferring
130 meg of data via an answering machine.
