Anyone else think iPhoto is too slow? It's still usable, but it just doesn't seem that snappy to me. I have about 700 pics in there and when I open iPhoto it just seems like it crunches away on the hard drive a little too much. Does it do this to generate or fetch the thumbnail pics or what?? Just seems to me like it should be more snappy, no matter how many photos are in the library. Any rumors of an iPhoto update soon???
