I spent 2 hours last week sorting out the IT problem of an elderly woman. Microsoft fscking “libraries” present files without the tree structure, and so she could not find her files.
I have now taught her how to use Explorer to find files, configured her LibreOffice to look in the right places, and generally tidied up, but this is an example of a “feature” that to my mind should require explicit installation and also be quickly removable.
Apple has gone down the same path. There are many reasons why I would never buy an iPhone (about 64G of photos on my removable SD card being one of them) but one of them is that all my experience and training says that any general purpose computer without a proper file manager is not allowed in the house.
