I've been using Apple Photos to sync to my devices and playing around with it, getting familiar with it since it launched. One thing that puzzles me is that with all of the talk of syncing between by devices, Apple still hasn't been able to let me sync Albums I've created on my iPhone/iPad to back to the Mac app. Sigh... Another instance: I made some favorites on the Mac app and chose to have iTunes sync those to my phone. But low and behold, the photos I've favorited on my iPhone created its own Album and are separate from the one I created on the Mac, so now I have 2 Favorites albums on my device. One made on the device itself and one I made on the Mac app. It's little oversights like this that make me say Apple's software is half baked.
