The keyboard is one-half of the way you interact with your PC. As someone who writes for a living, I spend hours upon hours pecking away at letters, trying to string a bunch of words together in a semi-coherent manner.
In other words, my keyboard is very important to me, and I’m pretty picky about how it feels. But my interest in mechanical keyboards started way earlier, and was borne more from my gaming habits than any practical need to be more productive.
My first mechanical keyboard was a SteelSeries 6Gv2 with Cherry MX Black switches, and it was a huge step up from the mushy laptop and flimsy rubber-dome keyboards I had used before.
