Ok. I'm close to your age and about to graduate in the spring with degrees in physics and applied mathematics. I have a similar background to yours (entrepreneur, software, and webdev, but not as much on the hardware side). College is valuable not so much for what it looks like on paper, for much of what you said about getting hired as an 'older' engineer is true, but for shoring up your knowledge with formal training. Also, I have had several really good ideas come to me in math classes over the past few years. You never know where inspiration will come from. You will also be immersing yourself somewhat in the culture of a younger generation. There is value to that especially if you plan on marketing something to an Internet market that largely consists of their demographic. You will also meet a lot of people and those connections are terrific, and not just for networking value. But, ultimately, what jborden13 said is true. You shouldn't make a big commitment like that if you don't truly want it. I loved it.

For me, I feel like entrepreneurship is like touching butterfly wings; you'll never be the same again and probably not very happy in a "job". Good luck
