I have an iPhoto '08 and wondering if I should upgrade to '09 or '11? Am I missing anything if I don't have the upgrades? I'm happy with the '08, it seems like I have the features already in the '09 like faces, places and facebook integration. I think the only thing missing is the full screen feature in '11? Is that worth upgrading? I know a lot of people having problems with the iPhoto '11 so it's probably not worth upgrading but then is it worth upgrading to '09? Any help or suggestions will be greatly appreciated. Thank you.
