Probably the #1 reason I like to use Lion is because of its support for full screen apps, and there mission control works better in the long run than spaces, but program compatibility is also an issue - there just isn't anything Lion only to really justify sticking with it over the stuff that's SL and earlier only.
Now from what I remember, when an app is full screen using the non Lion API, the dock isn't accessible, which makes switching programs a bit of a pain, but if the hot corners are still accessible then it's less of an issue. Can anyone who's using SL test how that works? Could I easily have 3 programs in full screen each taking up one space, and then have the 4th as a regular desktop? Or would I have to get out of full screen each time before switching?
