I can open a program in my quick-launch-bar with one click before you even typed the first letter of that program.
Maybe it's not a design feature, but it gets in the way.
(And yes: I'm using Windows 7 with the Windows Classic theme.)
I have a bunch of programs in my dock and I still prefer to open them with Alfred a lot of the time. If using 'CMD+space, ph, Enter' for Photoshop takes any longer than using quick launch then it's only by a minute amount.
