I find that I may spend more time parsing the result from an analog clock when someone asks me to say what time it is (generally the problem is when I perceive the minute hand to be halfway between two of the markings). HOWEVER, an analog clock has a key advantage for me over a digital one -- 7:34 when I have to leave at 7:35 does not make me nearly as desperate to go as when my watch gives the same reading. I think it's because digital clocks make me see the glass as half-full (since I always know exactly how much time there is left) while analog clocks make me see the glass as half-empty (since my watch is almost always at least two minutes off in some direction no matter what I do).
