Yeah, I've worked on embedded systems (some projects involving automotive and heavy machinery), and the amount of penny-pinching they used when selecting components was pretty crazy. On one project I worked on, they didn't want to spend an extra 30 cents for a microcontroller with more flash, so we had to be very cognizant of every byte we used. Flash was so tight, our firmware would only fit if we used the highest optimization setting on the compiler (making debugging very difficult).
