It depends on your specialty.
I majored in Radio/Television production, where I learned stuff like videography, audio mixing, video editing, and stuff like that, and I learned how to do it on professional equipment. In the two internships I've had, I was not given an opportunity to learn how to do any of that. Also, most TV stations don't have training budgets these days to teach people how to use their equipment. They want us to already know how to do it.
There are some things it's simply easier to learn how to do in college, where you actually have access to the equipment you'll need to operate in your chosen occupation.
Besides, college is where you make your real friends. Not work buddies, or high school clicks.
I think it's worth it.
