I enjoy selling people things that I've written the firmware for and that I've done at least a bit of the manufacturing on. It helps me to think of my customers as real people, even if it's just someone who bought my thing on Amazon. I don't get how people who don't feel that way work. I'm sure they do, and good for them, but I can't really grok how they work.
