There was one place, an owner of major personal and small biz accounting software for your PC, that I learned earned it's reputation.
No matter how early I got in -- and I tested the envelope -- there were people there earlier than me. No matter how late I stayed (and tested that side too) there were people who stayed later than me. The place used to go through keyboards because the sweat would pour in and short them out.
IF you know what I mean. ;)
I am also a DOT NET developer. I am fortunate to work at a company that treats its people well. In spite of the billions that pass through my software, I have not had to replace a keyboard for sweat, at least not for shorting. My sweat etches watches and removes the letters from keys, if that counts.
