It turns out that Physics was a great intro for my particular job. I started as a digital electronics design engineer and the electronics part could be handled with the few courses HMC offered. The tough part was understanding the complex interrelationships of the functional blocks of the system. My physics background helped in this area although I did spend some intensive time reading electronics books. As time progressed, my job became more of an architectural endeavour and that was where physics really started to help: architecture involves understanding the big picture, not just the details of electronics but mechanical, thermal, software etc. At one time or another I have used almost every branch of technology. Only physics gives you enough understanding of theory to let you jump in and start swinging no matter where you land.

I'm currently finishing my PhD in Biology here at UCSD. This was a big change from physics and I am not directly doing much physics related research. However, I think my physics training was very important. I learned how to be a clear, critical, scientific thinker which has served me well here. Having a physics background in no way hindered my applications to biology graduate schools. I think most schools considered it an advantage. The field of biology is becoming much more analytical and the perspective I have with a physics background is quite useful. Now that I am looking for a job, I think having a background in both physics and biology will help a lot.

My point is that the baseline skills for success in industry (I believe) are common sense, good communication skills, a reasonably broad background in science and decent computer skills. There will always be a market for bright people who satisfy these criteria, and a physics degree is a big plus for the applied science shops.

I would say, using myself as an example, having a Physics background is a tremendous asset no matter what field one decides to go into. I really think that the problem solving skills I learned as a Physics major have helped me in my Engineering work. Also, since Physics is so fundamental to everything else (perhaps my view here is a little jaded?) there is no way to go wrong by learning Physics first and then moving up to other disciplines. ('Up' in the sense that 'C' is a higher level language than 'assembly'.) And now seems to be a great time for well-skilled scientists here in the Silicon Valley. The group I am in at IBM is concerned with magnetic disk media and most of the PhD's are from Physics/Material Science backgrounds.
