It is impossible for anything related to using computers to be intuitive. Every aspect of it is either directly learned behavior, or extrapolated by reference to other learned behavior. Most of the issues described in the article are not the result of unintuitive designs per se, but the result of inconsistent designs within the same context. Inconsistency makes it difficult to extrapolate patterns out of particular experiences that can be applied elsewhere. But resolving this is just a matter of reconciling interfaces to consistent design patterns. The idea that the concept of a disk image is somehow inherently unintuitive is not really valid; and, in fact, the process of using a disk image and using a zip file to install applications are really two variations of the same thing. "Disk image" is just a particular type of file archive in the Mac world. It's misnamed, but that's not a problem for novice users who don't otherwise know what a disk image is; it's a problem for experienced users who know what "disk image" means everywhere else.
