I debated with myself on whether to use "naive" but it seems the most appropriate description. I barely know Woz outside of a 3-hour lecture but it appears that Jobs took advantage of his naivete, lying to him on multiple occasions. It worked out (financially) for Woz and he seems to have a great attitude about it, one of the reasons I admire him. He seems to successfully walk the line of not caring if people take advantage of him while not getting wrecked. I think it fair to consider that a facet of being naive.
