I'd say yes. My powerbook had several weird problems (culminating in a "faulty logic board", according to the computer repair store) over the first two or three years it was covered by Apple Care. (Of course, now that the warranty is expired, the comp has no problems whatsoever and I've sworn I won't get a new computer until this one goes on the fritz...)

When you get that bill, you'll realize that parts are bad enough, but labor is an absolute bloodletting without some sort of extended warranty.
