TUAW Review: iPhoto '09 is a pretty picture
As noted by Robert yesterday, the first boxed copies of iLife '09 reached users today. The two iLife '09 apps that have changed the most are garnering the lion's share of excitement this week. iMovie and iPhoto have some rather dramatic improvements, and I'll detail the iPhoto changes here.
Before you install, please note that the iLife '09 setup will nuke your older iLife apps. You'll need your original install disc to revert. I ran a Spotlight search and those old iLife apps are nowhere to be found. If you think you might want to roll back, be sure to back up your apps and your iPhoto library beforehand.
When you start up iPhoto for the first time it updates your libraries and starts an immediate search for faces in your photos. That search goes on in the background, so you can do other things with iPhoto at the same time.

When I installed iLife ‘09, my version of iMovie HD (from iLife ‘06) was put into its own folder labelled iMovie (previous version), which is nice since the new version lacks the timeline feature.
