What's the thing with DS keys, anyway?
(Thanks to DT for the image.) In the '80s, keeb makers switched to cylindrical keys, pretty well en masse. They must've had a reason.
Was it simply because cylindrical keys were cheaper to make? Or were studies done, surveys taken, and most people found cylindricals more comfortable and/or faster? And the DS revival is pretty well a novelty thing, powered by people such as us, who find the older look amusing?
