I was in Best Buy today playing - scratch that - drooling over the 13" MBP that I'm going to get for Christmas. I was running iPhoto (and it appeared that everything was closed except the finder) and I was getting LONG periods of the spinning beach ball. There seemed to be quite a few photos in there for the demo machine. Is this a common thing with a large photo library? I'm sure the fact that it was a demo unit with God knows who doing God knows what to it, but I was wondering if that common? Is it really worth it to bump up to the higher processor? Or would upgrading the RAM (that's my plan in the future) take care of it? Thanks!
