Had mine for 4 years as well and have slowly worked up to almost exclusively using it.
Keyboard, though, yeesh. As a proper touch-typist, I get annoyed at smaller things that most wouldn’t notice. There is a modifier key lag that is probably about 50ms. For instance, if you hit shift, you have to wait 50ms to hit A to get a capital A; it’s something I’ve had to adapt to.
I would like to get another machine as a backup/upgrade but the Librem 14 lacks a right-side full-sized Shift key which would be intolerable.
