The State of the Apple Developer Ecosystem

Except for the notable omission on the Mac of any system-wide iCloud sync progress. Remember how I spoke of Ubiquity earlier? That’s the subtle differentiation with Dropbox – by saving the document to iCloud’s location in the Save panel, your document is “in” iCloud. You’ll see a “Waiting…” status for the document in the Open panel if it’s not yet been transmitted to the iCloud servers. But if you quit the app? iCloud is designed to “just work” in the background and users trust that the document has been synced – a contrast to current user behaviour of looking for the reassurance of activity to make sure their documents are synced. – Nik Fletcher (emphasis mine)

Very interesting article on the convergence of iOS and OS X and the way Apple handles the Cloud.
