Add to the Model M the acoustics of a typical open office plan found at most startups and its unbearable. Its not uncommon to have a startup in a concrete loft type space with a group of people who insist on using whatever the modern $200 hipster version of a "buckling spring" keyboard is. It's "cred" man.
Unicomp sells actual buckling spring keyboards. They bought the tech from IBM -> Lexmark. Not bad keyboards, and pretty cheap compared to some of the hipster keyboards. I got mine with hardware Dvorak layout.
