My two cents: First, I'm actually surprised as to how much they are selling the dynamic perspective, and I think I'm actually more interested in how well firefly works. Dynamic perspective may be very "cool", but I'm not convinced it's not just another fad --- will it change the way I work with my device? Will it empower people? I don't see it as a transformative technology, and it's almost as gimmicky as (if not as gimmicky as) some of the extra "features" you get when you buy a galaxy S phone. Firefly has a chance though. I've spent some time with google goggles before, and I wasn't super impressed (have they updated it much recently?) --- on the other hand, I've had some success with Amazon's Flow app, in which you point your camera towards a product (in a store, for example), and it tells you the Amazon price for it. Will Firefly work well enough for people to rely on it on the host of use-cases that Amazon gave in its presentation? Other quick thoughts: Amazon claims some great battery life on the page, but didn't mention it at all in their presentation today. Also, it's kind of weird to think I would have 6 cameras on me at any point in time. Are those cameras accessible to developers, beyond their dynamic display apk? Lastly, how will this compare with google's "Project Tango" efforts?
