Recently I was chatting with a non-technical friend for whom it was clearly news that there were things other than Macs and PCs, and the concept of an operating system. So I started to outline things at a very, very high level, and after a time stopped and said: Would you like a diagram?

They said yes.

But I don't know enough to be able to provide anything but a sketch, but on the other hand, I don't want to be overwhelmed with detail, nor to overwhelm my friend. For example, I know that it's possible to run Linux on phones and tablets, but for now I'd like to stick with "off-the-shelf" options.


Very, very high-level first cut

What would you add? Please, get in touch.


There were no headings
in the main text so there
is no table of contents.
