For our Fall classes, we did not upgrade to ArcGIS 9.3 ® and we did not upgrade to Microsoft Windows ® Vista TM and we especially did not go for a new Macintosh lab with a Parallels or a Boot Camp, or whatever. The new copies of ArcGIS 9.3 landed on my desk right as I was leaving for my summer hiatus, so it did not get burned onto our new machines in the GIS lab or Scientific Visualization lab. We did get very souped up new machines in both of these lab, however, all of the specs I don't have at hand. Not that there are problems with ArcGIS 9.3 and Vista, we're just not 100 percent confident to make the switch. I see there is already a planned-for-November service pack for the new ArcGIS 9.3. Perhaps we'll wait until Spring to upgrade to 9.3.
