Running a computer without hard disk has its charms. Instead of putting all your stuff on one single hard disk, you 'll end up using several floppy's with a dedicated use. Instead of a folder on your hard disk called 'letters' or 'administration' or 'drawings', you'll be using floppies with these names.
So, when you need have finished working on a letter and want to do some drawing, you won't go to the 'drawing' folder, but instead you'll eject the 'letters' floppy and insert the 'drawings' floppy.
Handling documents this way gives you the feeling that you have more control over your computer, like having a closer relationship with the computer and the work you do on it. It is a feeling that is hard to describe, it is something you must experience for yourself. Maybe it has something to do with the fact that you can hold your docs in a small disk in your own hand, instead of them being stored on a hard disk hidden inside a computer.
