Edit: Just noticed the error in my thread title, I of course mean 'iCloud Photo Library'. I finally have my entire photo library perfectly synced across all devices and backed up to the cloud, I really couldn't be happier with the new service. Loving the optimised iPhone and iPad images, entire photo library on the smaller screens without using up a ridiculous amount of space. I really like the organisation of Years, Collections, Moments and that they kept the more traditional albums for those who prefer to organise manually. I'm also really pleased to see the project creation such as the photobooks is still in there, was worried we wouldn't see those again for a while. The editing, although very limited, is very easy to use. For how often I do advanced editing i'm happy to export images out to Photoshop. My only gripe so far is that there doesn't seem to be an option to shuffle photos when setting a slideshow from an album, or moment etc. Hopefully Apple will add this.
