> Smartphones are devices we use constantly, all day, probably some absurd number of times per hour, and it is a statistic that is surely going up.

I might be the odd one out here, but I'll often go days without so much as touching my phone. Either I have my laptop with me, which is better than my iPhone at everything save being a phone, or if I'm just looking to burn time I'll read my Kindle. I have friends who are constantly glued to their phones, and I simply don't understand the attraction.
