Not as good as Picassa, which is free!
Apple is selling what should have been a free update to iPhoto. Worse, it confuses iPhoto into creating multiple copies of each photo, and has a schizo stacking algorithm.The omissions are glaring.No duplicate finder, no layers, weak cropping and poor output controls.They have, however, jumped on the "pug-in" train to up-sell even more "features" which ought to come with a program like this.No where near as good as even Photoshop Elements, and even slower, even on fast hardware.Apple should go back to photography school.
