No, low maintenance and ease of install.  The price is important,
but 'Total cost of ownership/support' is the more than anyting.
With the Linux boxes I do not have to worry about the latest
worm or virus of the day.  I don't have these problems with
the Sun boxes, or my Linux boxes.

The Foxboro sales guys may be feeding me a line, but they claim
that Sun based systems are expensive because of the Sun licenses
included, and Foxboro is only 'passing the cost' on.  Where as
the WP 70's are cheaper due to lower licencing costs.  I like
the Linux solution, as it wouldn't come with a license cost, but
it is a solid OS that doesn't crash, and is not subject to
rampant viruses.

(The other line I hear from the sales guys is that 'everyone'
wants Windows bases systems, except me.  But every tech support
guy I talk to says that Unix is better, and only go with the
Windows if I am trying to save money, and even then, only use
Windows for WP, not the APs.)

I like the VNC's because it is easy to deploy.  I don't have to
install (or get the IT department to install) Exceed (or XFree86)
on a bunch of (their) PCs.  The most popular web browser will work as
a client.  And as a plus, the displays are very snappy with
VNC even over dialup.  Much quicker that Go-Global was, and
again, I don't have to try to install something on someones
PC at home.

Right now I am paying for DM licenses.  Since I do not need more,
right now the price point is zero.  If I wanted more, I'd be
willing to pay more :).
