IMHO, Unity is a work in progress. It definitely requires more resources to run than other environments and it requires some getting used to. I miss the good old task-bar for quick switching instead of moving the cursor to the extreme left waiting for the tab to slide in, clicking the appropriate icon which may then load an undesired window if the sought application is running more than one instance. I tried 'mousing over' the topmost left corner too.. it is also slow. However, unity is clean. It just hasn't figured out how we want to do what we want or who we are.
