My advice is to find something you enjoy doing, rather than what you think is marketable. You might guess incorrectly and have neither money or job satisfaction. But, don't stress too much about choosing a path. Your career will evolve over the years.
I agree. I enjoy both fields (CS and EE), so I think I should be OK in that regard. I'm going for a PhD because I'd like to teach eventually, but I'm not sure about what I want to do in between.
