As a bit of an eco-nazi, I don't see any of this as 'good', more 'features' every year, none of them particularly useful [do you really want to watch crappy music videos on a tiny screen, judging by my commute people do though] and more phones made/destroyed/in landfill.
Actually cell phones are a nuisance anyway, people can't walk and text or phone and text, so they bump into you. On bicycles, they risk life and limb [theirs and unhappily others] in London by using headphones [though admittedly a walkman or ipod is just as 'good' for this].
Despite what you see above, I love tech, having been in/around it for 40 years, but I really, really believe we need to step back from our current destructive and rather purposeless [except for making cash, of course] product cycles. Fat chance.
