I used to code at night with a kerosene lamp sitting on my desk. I love the light spectrum of a live fire.

"Portable" (they couldn't even fit in a pocket) CD players were the worst thing imho. Too sensitive to even small shocks, which was particularly annoying while taking longer walks, and draining batteries like crazy. I switched from cassette players to MP3 players, almost completely skipping the era of CD players. I've tried it once or twice because my sister had it, and never again.
