What is a Workstation? (What should GNU ...)

[Marshall Feldman]

Maybe we can focus the discussion if we ask about some interesting specifics:

Is a SUN 386i a workstation?  Why? or Why not?
If I soup up a 386 PC (on an MCA or EISA bus?) when, if ever, would it be
a workstation?
What is an AT&T 7300? (No jokes or flames please!  If IBM had made the
original UNIX-PC instead of its MSAWFUL 8088 machine, we wouldn't be having
this discussion).
