“Documents In The Cloud is unique. It’ll get compared to Dropbox, but the two are nothing alike. Dropbox is a conventional file system, extended to a remote server. In Documents In The Cloud, Apple’s created a new way of defining files and data, conceived from the ground up as a cloud service.
It redefines the concept of a file system. It also refines Apple’s whole product line. The iPad will seem less like an accessory and more like a primary computer once Documents In The Cloud becomes fully armed and operational; it encourages the user to forget about location and just assume that your iPhone, your iPad, and your MacOS are the exact same machine in three separate guises.”
