Similar age, similar history, although currently employed and having a blast with some new toys....

I re-entered the trenches by specialising in one hot technology (iOS) and producing a series of apps on my own account.

From your description, I suspect a CS degree would probably bore you and it wouldn't make a great deal of difference to your employability. That's not to dismiss university out of hand though. There are other departments where technology hits the road in a way that throws up opportunities all over the place. In your position I'd consider taking a few courses (not necessarily a whole degree) from a decent business/marketing faculty...real world experience can bring a lot to the table and they certainly do deal with fuzzy, hard to define, difficult, and above all, profitable problems.

I did a fascinating MOOC in gamification a few months back, if only I wasn't so busy....
