I have an Air, but I'm assuming this is an "issue" common to the complete line, if not all touchpads ever. I click with a single tap on the touchpad, and I've recently noticed that clicking as such gives a, roughly, quarter second delay. Which I found somewhat shocking; it probably decreases my efficiency somewhat, and is annoying. Fixes? EDIT: it's more obvious if you compare single click time to two finger click time. There's a noticeable difference.
