I love that there is no reply after Steve's final question. What DOES this guy make?
If anything, not making anything means you are less likely to be biased. Steve likes the iPad because he made it, not because it's intrinsically good. This biases his views on how it affects the software world.
Anyway, making something is good, but not making doesn't mean that your commentary on other people's products is not useful.
It means you don't have credibility to start with.
That seems be contradicted by his $1/year salary.
