Content! That’s the key.

As for the platform, i like the inline commenting, but I miss markdown. Also, it keeps the interface in Greek(??). I do have Greek installed as a secondary keyboard layout for all my physics/maths typing, but having a Greek interface (which I have to change everytime from “Browser’s default” to English, is weird.

My L420 had it (2011) and every ThinkPad I’ve used (many) ever since.
