One more thing (man, they announced a lot today): Google+

The new layout looks great, and the stuff they're able to interpret about your images is insane. I've created a couple albums and the way it's able to algorithmically detect good aesthetics is actually surprising in how good it does. I was pretty shocked...

I haven't played around with the auto enhance much, but it didn't really do much to the photos I tried it on. I also don't have any photos to try the "auto-awesome" stuff on, but I'll probably create some artificial tests to check that stuff out later.
