E-books most of the time and I've been reading on phone screens even before they became smart-ish. I still remember the joy of carrying books in the pocket, even if the screen of the Nokia phone I was using at that time was pretty small and books had to be in a very specific text format.

Paper books are fantastic and cannot be replaced when they are used as manuals. The memory of a printed page with nice graphics and of its relative positioning in a technical or scientific book that is read more than once is not replaceable by an electronic equivalent.

Finally, my sight does not improve over time and e-book custom fonts and size can be very helpful!

It is great to see a community forming for Joplin on Lemmy, even if getting used to the fediverse, lemmy-style, can be rough around the edges. Still, I was able to use both Mastodon and Lemmy on another instance to follow the discussion - that's truly nice!

If best GUI means configurable and pretty, I have not yet found an alternative that can compete with good old Xfce. It is the only modern desktop environment for which I can still modify the theme of the window decorations to my liking. It is fast and stays out of the way. Using it both on Ubuntu and MX Linux, both based on Debian.

Firefox most of the time, replaced by Chrome on one of my configurations, where Firefox would lead to graphic card freezes from time to time. Edge for Teams at work. Opera once in a while because I am nostalgic of the fantastic Opera mini browser on early versions of Android.

Also, Firefox on Android or Fennec on phones without Google Play.
