Ripley, that's true of the Unicomp, I use it for typing on one of my systems, and a modern mechanical with backlighitng for gaming on that same setup. There are so many variables in personal pref with them, there are multiple types of newer "cherry" keys, red, black, green, brown, I've lost track now. None of them beat the original IBM M buckling though, which works fantastic for both gaming and typing IMO. Back in the day of Quake/2 being the biggest online thing, every single gamer out there was always after the IBM clicky keyboards for the added precision.
It is the small things, like HTC said. The keyboard IS such a small thing in a system, especially in terms of cost, many think of it as an afterthought, or give little thought to it at all. Yet, 90 percent of your PC time is spent using it. It sort of reminds me of people who sleep on really crappy beds, but drive 100$k cars and live in a 750$k house - the one place where at least a third of their time is spent is where little concern is given.
