I'm a long time windows and linux user, just starting with Tiger. My most common frustration so far is that in Windows and Linux, I can have multiple windows open and non-minimized, and can easily switch between them via the task bar. I don't see a similar functionality in os-x. It appears to me that the only items that show on the dock are ones that I've minimized. If an app is open, but 'behind' another in Tiger, it appears I have to use Expose' to find it. In the other two OSes, I can just single click on the item in the status bar. Is there a way to single click to an open app that does not have the focus? This is pretty big...I always have lots of things running, and the task bar is a ONE CLICK way to switch. Expose' seems to be a minimum of a two click way, and a pretty clunky way. I'd love someone to explain what I'm sure is a simple way to have the same simplicity in os-x. Thanks!
