I'm new and just got my first Mac, an MBA13. I'm curious about the different video chat options and when I search google, its like an explosion of opinions. So, I've taken my question here where I know I'll get a solid answer. What is the end-all be-all video chat app? Is Facetime really a waste? Also, am I correct that when mountain lion comes out, iChat will be no more? one last thing, sort of a side note but, when mountain lion is released, I CAN upgrade my MBA to that right? thanks!
