I've used a few keyboards made in late 80s or early 90s, and some Cherry MX Blues were non-clicky on themóafter spending about 20 years in a box, but maybe they'd need some break-in period...?
keyboards: ErgoDox (80key, Massdrop #1 PCB, FalbaTech compact PVC case); Noppoo Choc Mini (2012, black); Phantom (7bit); QFR (2012, ANSI, Frosty Flake); TypeMatrix 2030 (USB)Ö (and a large collection)
pointing devices: Kensington Slimblade trackball; left-handed Hippus Handshoe mouse; Roccat KPM; Roccat Lua; Logitech M570 (switch swap); Wacom pen-enabled digitizerÖ (and a large collection)
notable past keyboards: Access-IS AKE120807/1/M, ErgoDox (stock Massdrop #1), Kinesis Advantage, Lenovo SK-8855, LiteOn SK-6000, Logitech UltraX, SteelSeries 6Gv2
preferred keys: linear switches (e.g., vintage MX Black w/ 78g springs) and thick Cherry POM keycaps
