Regarding the employment opportunities for physicists; I've found that physics offers a great deal of flexibility in choosing a career path. When I decided to return to the west coast and join IBM, I was also actively recruited by a teaching college, research university, national lab and I had a tenured position at Argonne if I had chosen to stay there. Presently, the job market is very strong for Ph.D.s.

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.

I love teaching (but then, I learned from the best), and love my research - it's trying to do both all the time that I am finding taxing.
