To accomplish all this, Apple is introducing iCloud Photo Library. Apple wants to make sure that anyone with both an iOS device and a Mac gets a seamless experience with their photos, same as they already get with everything from their iCloud mail to their iTunes music to their iWork documents. Increasingly, more and more of them own a Mac as well. Hundreds of millions of people own an iPhone, iPod touch, and/or an iPad. They're going to make Photos not just an app but a service for everyone on every Apple device. With Photos, Apple is saying pictures and video - our memories - are so important they're going to make them an integral part of iOS, OS X, and iCloud at the system level.

They were built in an era before iOS and before iCloud and while they've had some interface and compatibility layers bolted on, they were never rebooted the way iMovie and Final Cut Pro were in terms of interface, or Pages, Numbers, and Keynote were in terms of compatibility. IPhoto and Aperture are, by modern standards, old apps.
