I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn't work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I'd gladly replace if it broke.
Do you realize that calling it “Koscher” implies that any billionaire would secretly be a Jew? It's antisemitic propaganda.
Anyway, I don't think you got me. I implied that I was plugging peripherals on my Raspberry Pi, working on my university campus with better ergonomics than on a laptop.
