Comment Logitech K750 (solar) (Score 2) 452
Long story why. I used original IBM clickly keyboards (still have 2) also used cheap plastic clones of these and wore out keys on 2 such keyboards because they are from regular plastic material. Also tried Microsoft "Natural" - there's really nothing natural - they all suck and slow.
In the end, I came across that keyboard on display at FRY's and it felt amazing. Bought 4 since then. They are unfortunately, not the most reliable. I already had one die just after 3 years. IBM are still rock solid after > 30 years. However, I notice a drastic performance boost with these keyboards. It seems I can type more code in less time, and I don't mind paying for more of these.
Unfortunately previous model without the solar batteries even though looks similar, does not actually feel the same. It feels "slow" as normal keyboards. Yet the K750 feels like the code just appears itself. When I go to work somewhere, I take one with me as well.
