Tome – R10/DECwindows, I believe, was our first port to an Xwindoes
platform, followed by R11 for Sun's OpenWindows. We're not ignoring
Xwindows. As I understand it, however, SCO's Open Desktop doesn't have
backing store support (or at least it didn't the last time I heard), and
lack of that was a major stumbling block, since it would force AutoCAD to
perform a vector redraw (rather than a fast bitmap restore) if a portion of
its graphics window is obscured by another window and then brought to the
top again. Performance in such an environment would not be good, and our
customers crave performance. But even performance isn't enough; when the
SCO XENIX version of R10 first shipped, it offered far and away the best
performance of any platform, but relatively few licenses for it were sold.
I don't see how Autodesk can be "ignoring the realities of the
marketplace". We're participants in the marketplace and have received
clear messages from it. We've also got a business to run, and shareholders
who expect to see a good return on their investment.
