So, with so little hardware news (if a 17" laptop can be considered "little"), the Apple booth was all about iLife and iWork.
I spent some quality time with iPhoto 09, alone and talking with an Apple staffer (who was a photo geek too), and here are my impressions.
For me, the main new feature is the integrated geotagging of pictures. Simply clicking on places in the source list shows a map displaying the world with pins indicating where you shot your pictures (in a very iPhone-ish style).
