Robert-
I don't know how common it is, but we also use MI and AV in the same office.
We also use AutoCAD 2000, CorelDraw and Photo-Paint, as well as everything
from the Microshaft Office package.  We have AV because of preferences from
our Head Office, but primarily (>95% of the time) use MapInfo for mapping.
Our drafting dept. creates maps for geological research and mineral
(diamond) exploration, and we also make presentation material, posters, and
slide shows hence the other drawing packages.  Anything graphic, we handle.
With the use of the Universal Translator, we can export MapInfo files to
ArcView SHP's in order to share with other users, so we don't need to draft
or buy data twice.  Same with DWG/DXF files which we still get from
consultants, as well as all the original digitizing and mapping work we did
before MapInfo (also the need for AutoCAD).  Then you add on Access to query
data from the database and Excel to give that data to others and to make
graphs.
All in all, I'm sure it's not too unusual to have more than one piece of
software to get your job done.

In your case, you probably don't need to upgrade everytime a new AV comes
out, as most of the functions you use it for come with your original
version.
Regards,
Jason
p.s. If you ever get the time, take a scan through some Mapbasic (MB)
programs - it's not to hard to pick up the basics of the language.
