I keep one on dead tree media in chronological order. It gets used at least once per week as if it were a lab notebook, for note taking during debugging firmware or hardware prototypes, less so during initial development for roughing out architecture and doing first pass state diagrams. As for utility it's indispensable when trying to recreate something like test bed setups months later. In the old days it would have been useful evidence in patent litigation.
Those days $DAY_JOB bought us high quality and very pleasant to use pricey half-bound (each page bound in front of a perforated copy sheet to tear out) and page numbered engineering notebooks. That's no longer the case with the new first to file regime.
