Gotta say, the new additions to Photos are IMPRESSIVE. Overnight while my phone was charging, it wrangled up some amazing memory videos, identified many faces with almost complete accuracy (and allows for merging i.e. if there are photos of someone from many years ago and now as well), and the search by objects works quite well too. Blah blah google photos blah blah I'm fully committed to iCloud photo library and actually enjoy the service, works seamlessly across all my devices, so this is an awesome update that seems pretty fully baked, especially given that it's all processed locally.
Also, time to leave notifications for public transit are awesome so far, spot on, similar to Google Now. Perfect for this manhattanite.
Just out of curiosity: how many photo's do you have synced in iCloud Photo?
After a night worth of charging and most of the time today, Photos has found 3 memories and 0 faces (still syncing, progress bar around 4-5%).
