very good point! we have a mathematician in our engineering team. one of our teachers (software engineer) was working toward his PhD in nuclear physics, but stopped in the tick of it because he wanted to work in the IT. you really just should do what you think is right for you. if you wake up in the morning and you're happy to go to work, then you know you've found the right thing for yourself. a major in CS doesn't restrict you. it's quite the contrary. you can choose to do a lot of things, since IT does not only consist of programming positions.
