Ok, the Face Movie feature is awesome. Picassa gets to stay on my system for that one feature.

And the face recognition seems to be on par with iPhoto 9, along with the ease of use. I created my own smart album in iPhoto to show untagged faces, but having the unnamed people come stock as it does in Picassa would be helpful for a lot of other users.

Picassa is really impressive to me, and I'd highly recommend it to any of the Windows people here.
