+1-1I think Apple wants to have Photos 'behave' the same on any device you use, bit like iWork apps. All photos are accessible on all Apple devices, and any modification you make gets pushed to all devices. Plus, all modifications can be made on any device, including iCloud.com. Somehow that bothers me, as I don't think a webbrowser can do the same things as a dedicated OSX or iOS app. But I'd love to be surprised by Apple. The often do, just not always in a pleasant way.
