This debate is silly. It's simple, can an average person use the app/watch combination as would reasonably be expected? The answer is no. This is clearly a case of marketing getting ahead of themselves. It's like promoting a car that is too wide to fit most roads. Sure the car works but you can't use it therefore it's useless.

Qantas should have field tested this app. It's not unreasonable to expect that, in fact, it's essential. In the IT world we call this UAT, user acceptance testing. It's a development fundamental. If you fail UAT and start arguing that it's actually the user's fault then you've both failed because no matter who is to blame it still doesn't work.
