First paragraph snark aside, I agree. To say that any tech market is completely closed to new entrants seems slightly ridiculous. Sure, the barriers to entry have increased - if you're chasing mass-market appeal, a strong app platform is as important as excellent hardware. However there will always be some niche to serve or an opportunity to tackle bloated or less open, established competitors. I think Josh's option is very biased and colored by operating in a certain type of environment. Not that it's any less valuable or valid than any other, but I disagree with him.
