Ergonomic keyboards designed to make typing more comfortable (and reduce long-term injuries) come in many shapes and sizes, but it’s safe to assume that Reddit contributor dapperrogue’s functional Pineapple keyboard, modelled after a hand grenade, is a design you’re not going to see Logitech or Microsoft adopting anytime soon.
