I’m in LOVE with iPhoto ’08 so far. I love the idea of “events” – it makes so much sense to group photos together based on the timestamp. You have an option to control how “close together in time” photos have to be to be considered part of the same Event.
I’ve got all of my photos on my MBP arranged into their proper Events – had to manually merge some that spanned several days, and I have a “Family Photos” and “Random Photos” that act as catch alls for the pics I take that aren’t really related to any particular Event.
So far, iLife 08 is an AWESOME upgrade, and well worth it if only just for iPhoto 08 and iMovie 08. Very well done, Steve!
