1) Network works well in metro for me mostly, though it's a valid point that it might suffer here and there. But metros is just a smal fraction of the possabiities we - and retailers we talked with - see.

2) It won't be 20 apps, becuase there are only a few companies in the world that has sophisticated algorithms enough - many algorithms you can read about on the web are not realiable enough. So far no one has done a consumer product but hundreds of QR-based apps, I would say that this say a bit how hard it is. Anyone can craete a QR app based on some open-source libs.

3) Well, our demos show something else - ~1-2 seconds.

4) Flash. And scenario for scanning stuff in night dark is...not really a descent secenario anyway if it's that dark people have hard to see.

5) That's an assumption based on today's reality, because no viable succeedors are available yet that do more valuable things. Yet I haven't heard of anyone using QR codes more than once or twice for fun even though it been "hot" since for half a decade or more.
