Re: New iPhone/iTouch App idea
Well you wouldn't really need WiFi at least with the iPhone because you could just use your network signal. But i think the problem would be that confusion part you noted: that despite the technology, you'd see longer lines at the FastPass because people would be futzing with the technology, fumbling with the phone, etc. Plus, there would be the risk of signal loss or the app crashing. At least with paper, the proof is right there.
Plus, personally i would fear that it would just encourage the use of portable electronic devices, especially in a situation that could already be tricky because of the technology. Can you imagine someone chatting on the phone walking up to the fastpass line and having to beg off the phone so they could show the cast member their phonepass?!
