All true. It goes even farther: hiding the file structure, and even the concept of files. Ask a nontechnical Windows or Mac user where their files are stored - they have no idea. Ask if they are in the cloud - no idea. Worse - just as with UIs - there is no consistency where different apps store their data. We also shouldn't forget the idiocy of hiding file-extensions.
To add insult to injury Windows lies to non-English speakers. In German, for example, it will tell you your home directory is in "Benutzer", but there actually is no such directory, there is only "Users". These attempts to hide complexity wind up creating confusion and more complexity.
