For example try this at an Apple store: stand at a Macbook and open several apps at once, close them, then reopen them, then do the same exercise on an Air.

Well the Macbook at the store probably don't have SSD's installed.

I would assume that if I replaced the HD with an SSD, the MBP would be faster because then it'd have the processing advantage.
