I think the nice thing for me is that it creates a hierarchical method of finding my next activity - app > window > tab The MS Windows-specific alt+tab model means way too many things to choose from without context. What I'd love in Mac OS X is a standard way that I could drill in - with enough context - using keyboard short cuts to window and then tab level. Perhaps something like that exists, but I haven't found the consistent way of doing it yet!
