Actually Bob, I've written 5 commercial navigation products, 2 of which are currently being sold every day now (well, the Palm one has seen sales fallen off). In addition, I've done major user-interface consulting projects for the largest companies producing marine navigation products.

So now I guess the obvious question is, do you actually know how to write code and did you do so for your "5 commercial navigation products"? A simple yes or no answer will suffice... along with a mention of the products.
