But it does seem, given all the annoying cloud-based features I have to turn off after just loading Mavericks, that Apple wants to move in this direction... for all devices, desktop machines included. 🙁
I seriously doubt Apple wants the guy with 6TB of RAW files in their cloud.
Even Adobe probably does not want that customer bringing that much overhead to them.
Apple supports 2 OSs and a huge chunk of their customer base, including many professionals, require persistent connectivity. So Apple pretty much has no choice but to build in similar processes, library structures, and interfaces between the Mac and iOS.
Power users are a cost centre. Some bemoan the lack of certain features in Aperture not realizing that the market for many of these features is minuscule.
Remember: iOS is on devices where Apple and the consumer expect NO desktop computer at all in the mix. None. The general consumer trend is away from any home computer and all towards mobile devices supported for storage, transmission, and presentation on the cloud. The home darkroom PC for power users it turns out is fractionally small market. So Apple looks to be building a platform with the Mac where Photos will be a container with an OS-level library structure (photos have become like fonts). Those small user bases who demand atypical features can source their needs from an app.
This will contrast with Adobe who are tied almost wholly to the desktop and its stalled and even declining sales. Adobe will have lost almost the entire mid- to low-end market to Apple's built-in free app, and they will rely on professional pricing via subscription, monolithic software that needs to phone home every 90 days.
It is Adobe that looks to be in trouble in the long run. I am not sure they can adapt to the mobility, non-desktop, and cloud services in the same way as the company that controls all this at an OS-level.
