I don't think I've ever met an engineer who used it in college. Except it might be like Messiah's quantum mechanics book -- something you read after you already understand the subject matter. That's why the second through sixth readings are the best. ;-)
But I think the physics students were learning electronics for a different purpose, to support laboratory research, which depends heavily on electronics. The course was expected to be accompanied by a lab, and we had a lot of chances to learn about making and breaking things throughout our degrees. Maybe the electronics course helped us figure out which ones of us became experimentalists, or theoreticians.
And both Electronics and manufacturing were also much more primitive in those days. Real products were closer to our hacked-together prototypes than they are today.
Hey, I did! And I had to teach out of it... that was an experience. (I distinctly remember pulling it out in class one day, as a TA, to show the students a figure that was particularly good... and got yelled at by one kid because "that's not our book" and "we shouldn't have to read that". Even the other kids rolled their eyes at that one.)
It really is a text that's made for physicists and hacker-types. There is a ton of great information on building one-offs and prototypes. Not so much for getting products out (so. many. trimmers.).
