I prefer digital books because of the following points:

• There is a book price control in Germany, meaning that you can’t get new physical books cheaper. This does not apply to digital books.
• They take less physical space.
• I can read them everywhere with either my Smartphone that I already have with me at all times or my tablet. I do not have to plan to read a book when I’m on the go.
• I can quickly search for something in a reference book if I have it in digital form. This is not possible with physical books.

Only downside:

• I need to have a device when I want to read a digital book. And this needs to be charged. But this is rarely a problem.

What software did you use to make this diagram?

You can also download the *.vsix file of the desired extension from either Github or Microsoft’s extension marketplace and install it manually by clicking on “Install from VSIX” in the Extensions menu.

This obviously doesn’t solve the update problem and it is also questionable if this is in terms with the “Microsoft Terms of Use” of the extension.
