My grandfather worked for IBM starting in 1979 till the mid 2000's. Towards the finale of his career, he worked from home, so a lot of IBM hardware ended up accumulating in his home office. One day, years after he retired, I was going through the closet and I saw a bit of beautiful beige sticking out from under a pile of other useless keyboards. A 1987 IBM Model M. I nearly had a heart attack. It was in perfect condition and only needed a bit of dusting. It has been my primary keyboard ever since, no modern mechanical has come anywhere close to matching it for me. The noise drives my coworkers absolutely bonkers though.
