No, why would I?
I do now...
And by "adding items," I mean you can "clip" the applications themselves into the taskbar. Not just a minimized window. Or do you not know your own system now?
xp and vista always could, but it wasn't drag and drop before.
then you had to insert a folder to display all it's icons down there, inc desktop if you wanted.
but no one gives a forget about bells and whistles. only a mac user would learn about an OS from a commercial lol.
7 is great because of it's perfect working compatibility mode, and forced 64bit support on anything you please.
older versions of mac OS cant even play it's own apps once upgraded past a certain year.
