What keyboard do you use that you absolutely love? How does it make you computing experience better?
I have issues that make my keyboards suffer [1]; I have refurbished and killed real IBM Model M keyboards from the 90s, and they lived an average of 3 years under my hands. The new one I'm using now has 2+ years and hasn't fallen yet.
By comparison the fancy Logitech "mechanical" i tried after killing the last of my old Model Ms lasted approx 6mo.
[1] psoriasis on my hands, so my keyboards are subject to a constant rain of acidic skin dust and blood, and frequent cleanings.
