We briefly interrupt the on-flight entertainment for an update on e-ink monitors (see previous posts here and here). I am happy to report that during the summer my e-ink monitor worked extremely well. Writing as I am doing now with the sun shining through my window is fantastic. My entire summer production — including this survey on non-abelian combinatorics — was written exclusively on the e-ink monitor. I don’t think I ever felt so good about a piece of electronics since relentless market pressure forced me to abandon Amiga.
