Clarify "multitasking"

I think by "multitasking" he meant being able to see multiple windows at one time, not simply having multiple applications running. I use that ability all the time in my work, and having to alt-tab between windows would be a huge show-stopper. If GNOME 3 really does not allow you to have multiple windows visible on the same workspace at one time, then it's not for me. (I haven't tried GNOME 3 yet, so I don't know.)
