cuz its a *****torm waiting to happen with noobs not knowing what it means and just enabling it cuz the icon looks pretty. releasing something without having the other part ready for another half year or so seems very microsoft to me
Typical use case: my mother. She takes photos on both her iPad and her iPhone and wants to see all her photos on both devices. Her eight year old MacBook doesn't get used much and it's for word processing Rather than casual browsing and photo viewing. In this scenario, iCloud photos is great because all her edits will instantly be saved, and her videos too. Photostream doesn't need to be on and all her photos, pretty much forever, will be backed up online.
