I was in an Apple Store the other day to scope out the perfect machine for me next year at school. I was looking at the Macbook, which are pretty slick. I ran the 2.66GHz MBP through its paces, Aperture, photoshop and the rest of the creative suite I plan on using. Anyway, as I toyed with it I noticed I could feel the hard disk seeking, and if I listened closely, without even putting my ear to the machine, I could hear the disk! I checked the 17 inch display model and I could feel the disk in that one too. With my current core2duo Macbook I can't feel or hear the hard disk at all, even if I press my ear up to the machine. I've even gone through two disks in this machine, the stock 120GB drive and a 320GB one I believe is from seagate, neither drive makes a sound. Is this a problem with the unibody machines? I think I would get too annoyed with this and I may look else where in a machine if this is a common problem.
