The fact is: this phone is really not for us, the tech-savvy hackernews reading crowd. To the best of my knowledge, this is one of the first biggest tech introduction that only has real value to the "regular" folks that came out of the silicon valley culture (ok, ok, Amazon is not a silicon valley company, but it's as if it were). If I'm wrong and there are products aimed mainly at "regular non-tech folks" that came out of sillicon valley, please correct me.
I am really curious as to how this will unfold. As I see it, most of sillicon valley innovations followed the normal adoption curve: go for the innovators, then expand your market until you hit critical mass. Some were slower (Dropbox), some faster (IPhone), but they all had a very big feature aimed at the tech savvy as well. This is why I think Firefly may be a good thing, it's the bait for the tech people to adopt it and then, hopefuly, it will trickle down to the moms and pops out there. Honestly, then, I think of it mainly as a curiosity than something I would spend $600 bucks to have.
