But less talked about it is the "journey" part.
As long one is in touch with personal motivations and goals, then college seems fine.
You're in no rush, financially comfortable, and as eager for experiences as you are your innovative product. I'd say college sounds like a cool idea. I'd just be careful to pick a good program, otherwise it could be painful/frustrating.
I'm about to go to college part-time with no professional necessity at all. I'm in a different spot than the OP. I don't have a first degree. But I do have a fine geeky career that I'm about to step out of to start a business (way less capital intensive than his idea :D ), and am going to college with the hope of learning a subject matter, but no real expectations. Just mostly for the experience.
