I have to agree with those encouraging the AF. My husband is 21 years in and still going strong. His degree was in Computer Science Engineering. The first half of his career had little to do with computers (in the traditional sense). This second half has everything to do with computers, but he's not sitting at a desk actually programming or anything himself. Don't discount computers as a viable career path, you'd be amazed at the options out there.
I concur with the one who said to look at a career path in Information Operations. That's where my hubby is now. And it's pretty exciting stuff.
I'm gonna brag on my hubby for just a bit here...since we're sort of on the subject.He was just selected to be the Vice Wing Commander of the 688th IO Wing out of Lackland AFB. They are involved in what is essentially the bleeding edge technology of cyber warfare.
Whatever direction you decide to go, you just about can't go wrong with starting out Air Force. Even if you decide after a few years that it's not for you, those few years will be invaluable to your future. You'll have doors opened to you that would not be otherwise. And you KNOW of opportunities and possible paths you might take that you never hear about in our day to day humdrum lives where "computers" means little more than sitting at a desk writing code or linking networks and answering tech support calls.
