iCloud is fantastic. I take photos on my phone and they are up in the cloud in a second. Then I have access to them on my computer, iPad, phone, any computer / anywhere. You can use Apple Photos to edit them and the edited version as well as the unedited original version are both available. It is a great and easy to use system. I buy 200 GB storage for $3/month.
The seamless integration of the entire thing is what makes it so easy to use.
