Anyone who uses a keyboard all day for work knows the difference that the right keyboard can make in the quality of daily life. I’m continuously on the search or the best keyboard (which really just means something better than I have now). This page is intended for others who are picky about their keyboards as well. I plan to share my experiences with the various models of tried so far, and also collect and list information about keyboards I’d like to try in the future.
Keyboard comfort is in the hands of the typer, that is to say, opinions about keyboards are always subjective. I don’t claim to be able to say what’s good for everyone, so instead I’ll just talk about what makes a good keyboard for me:

• Light touch: I shouldn’t have to press too hard to depress each key. That’s not to say that it should depress just by resting my finger on it, but keypresses should feel like a ‘flick’ of the finger, rather than a ‘press’. And they should feel like ‘taps’ not ‘slams’. The easiest way to tell is whether my hands feel tired after a period of typing. I have yet to encounter a keyboard that is too light. I suspect that’s because people think the light touch indicates cheap quality, so manufacturers err on the side of stiffness.
• Tactile response: You want to know when the keypress actually took. You want to feel it because if you have to wait until something shows up on the screen, its often too late. I also prefer that the tactile response is not a
  result of the fact that I’ve pressed the key so far in that it has bottomed out.
• Ergo layout: In general I don’t mind ergo layouts, but I do if they make me unable to type on non-ergo layout keyboards. Laptop keyboards with keys in funny places also have this problem.
• Key travel depth: I’m currently undecided with regards to this parameter. I think if the other parameters are done right, this actually matters less.

Keyboards I have owned or used (comments to be added soon):
