I had no problems with Apple Dropping Final Cut Pro 7 and replacing it with a completely different program, Final Cut Pro X. The deficiencies of the initial release of FCPX didn't bother me either since I knew that Apple was committed to the software and would fix problems and add features back as time permitted. I had hoped that this was the case for Photos so I haven't converted my Aperture library. However after reading the review in MacWorld's June issue I now am thinking that photos is not like FCPX. Aperture is like Hypercard. When it is gone in OSX 13 Photos will still not have the missing Aperture features. http://www.macworld.com/article/290...n-iphoto-but-less-powerful-than-aperture.html The key paragraph reads:: Apple hasnt been simply creating a new photo application for the Macthis is the Mac component of the companys grand photography effort that connects the iPhone, iPad, iPod touch, Apple TV, Apple Watch, and the Web. With iCloud Photo Library, Apple is attempting to make all of your photosnot just the ones you capture with any one deviceavailable on every Apple product you own. So if you're creating an app that works on a 5.5" iPhone as well as a Mac you're never going to add back those missing Aperture features.
