The hosting budget goes to servers, not to peripherals. I use the $12 membrane keyboard from supermarket and I have zero latency issues. Voilà, my WPM is 94 and my deployments do not fail because of switch type.
The group buys, the "thock," the lubrication rituals—this is mysticism. You pay 300 dollars for brass weight and tell yourself the signal integrity is improved. It is not. The USB polling rate is 1000Hz regardless.
I will die on hosting hill before I die on keyboard hill. Voilà.
