Is Lightroom better and FASTER than iPhoto? I use iPhoto 06, i got 6000 photos in my library and its pretty slow actually. When i open one photo in full screen and scroll my photos with the arrows iphoto is slow, and iam getting "loading" all the time. About 2-3 secs to move to the next picture. The pictures are about 2.2MB each and my system is a powerbook G4 1.67 with 1.5GB ram. Is this normal? Is iPhoto slow or my mac?
