Cannot stand tapping. Drives me completely insane, always "clicking" without meaning to when I just want to move my finger a bit...
I've turned off tapping on my trackpad.
I constantly click the wrong places with it on.
Parkinson's?
Love the tap, been using it with any laptop for over a decade. I don't use the Drag anymore, but that's Dell's fault since I was stuck with a Latitude for a couple years at work. Drag actually works on an Apple, I may start using it again when I get a MBP.
