To be fair, I think a lot of today's software is also written on a Model M, even if it's plugged into the latest and greatest. I really enjoy mine, I know a couple other co-workers who have one too

I wrote a lot of code on a model M at my first job. I should probably get another, that thing was phenomenal.

The Unicomp Model M continuations are still good, as well.

im typing on one right now. i have to figure out how to clean the keys, some have some coffee stains :)

The plastic is pretty durable (PBT) - you can scrub with them with dish soap. Isopropyl Alcohol should be fine too if you want something stronger.

Can't blame him, the tactile and auditory feedback is awesome. Mine is 1 year older than me and still works great.

Typing on a Model M makes me want to type more and more.
