I type a lot and I type fast.
Yup. I'm good for about 90 wpm when I'm on a roll. I can go faster but that starts to introduce errors. Errors slow me down significantly, meaning I can't maintain speeds higher than that. Like hundreds of thousands of words at just linux-tips.us. I wear the caps out.
I do have a few perfectly working M model keyboards from back in the day. They just need an adapter and they work fine with USB. I just don't bother using them - but they're very tactile. I'd probably use them, as I like the amount of force required, but man aren't they loud.
Amusingly, I've failed two classes in my entire academic career. (That's a rather extensive amount of time in academia, about twenty years in total.) I failed typing in high school. I failed keyboarding (note the difference in the name) in college.
I just couldn't make my fingers do what they needed to do. Then, along came IRC. What I did at that point was just memorize the backspace key. If I made a mistake, I forced myself to backspace far enough to fix the mistake. Because of this, I use the wrong fingers on the wrong keys, but my speed is all down to chatting with internet strangers.
Depending on what my fingers are doing, I may press the 'r' key with my right hand (for example). I used my left hand to press the 'y' key sometimes. I only ever use the left shift button and I only use the right thumb on the space bar. Which is how I end up wearing those two keys out pretty quickly. I know that it's hard plastic, but there's a literal worn down section on this current keyboard.
What I should do is experiment with some of the fancier keyboards. I should be able to get a quiet keyboard that still requires enough force on the keys. There are all sorts of choices out there, and they can be repaired or reconditioned by replacing the caps and springs. Some combination of those would probably suit my needs.
Or, I can just buy a new cheap keyboard and mouse combination every six months or so to have on hand for when I feel like replacing a keyboard. I don't need any of those right now, as I have some spares already here at the house. I spend like $30 on a keyboard and mouse combination. I prefer them to light up, but I don't want that to be fancy - I just want them to be lighted in pretty much any color. I'm not picky.
