Do you want to make money? Or do you want to have fun, regardless of the money making potential?

If you want the former, go with the safe option that solves an obvious problem. If you want the latter, go with the fun option that uses the cool tech you want to play around with.

Then again, why is it a choice between one or the other? Could you find a problem to solve that the cool tech you want to use just happens to help you solve? If so, do that.
