Fair enough, I suppose. The article author was comparing submarine nav software to phone nav software though and google says there are 5+ billion mobile users.

Fair enough, I suppose. The article author was comparing submarine nav software to phone nav software though and google says there are 5+ billion mobile users. That's another couple of order of magnitude more. That'd explain why mobile software is more polished. I guess any kind of mass market product would be higher quality. The same argument ("number of eyeballs") has been used with open source software vs closed source.
