For me the loss of color is a major drawback. It seems the way Apple are going with dull uninteresting gray's. I mean I now have to squint at tiny icons & text to see if its a Folder or Project or what. Who thought that one up?
As for the rest there are so many plus points all in all worth the update. If there is an easier way to update all the libraries at one that would have been so much better but to either wait until you load a particular one or sit & go thru them all one by one to update them is a pain!!
Maybe they thought everybody has only one Library file. Most experienced user I would suggest use Referenced Masters & have multiple Libraries, right?
P.S. I have this sinking feeling that as iPhoto & Aperture become more merged that we will eventually only have one. Hope not.

I for one do not use referenced masters. I do have multiple libraries with well over 500gb of raw photos. I do agree that it would have been better to up date all the libraries at one time. With the new high resolution, Retina display computer coming out as we speak they will probably up grade all their Pro level applications to take advantage of it. So I rather suspect we will see a new Aperture X release shortly. At the conference they said an Aperture to follow would be a game changer. No body really knows what Apple is going to do or why. If they are coming out with an Aperture X, merging iPhoto with Aperture III makes since. They don't need three photo processors on the market.
