I think the issue with Lion and also with Ubuntu 11.1 is that the GUIs are experimenting with various tablet concepts which significantly alter some of the behavior. It's pretty confusing at first but I adapted to Lion after about 4 or 5 days. I still don't quite understand Unity but expect to soon.

I think most anyone who is willing to accept that the world is undergoing a transition into a world where tablets coexist with laptops, etc., will embrace this time as a period of experimentation, rapid change, and creativity.
