Both of my co-workers and my managers are still on 10.6 because of perceived concerns about 10.7, and the fact that our IT department wants to do a full reimage to upgrade to 10.7 or 10.8 rather than just running the upgrade. I actually have more problems with 10.8 than I did with 10.7, so I understand some people's reluctance to upgrade.
