QuickLook is a brilliant power user tool which I wish Explorer had - but, like many of Finder's features, it's hardly discoverable without either hearing about it first, or being willing to press random keys to see what they do (which many computer users are very unwilling to do.)

I agree that the hotkey for it is not very discoverable, but the default layout for the Finder toolbar has a button for Quick Look (it's in his screenshot, the one that looks like an eyeball).
