>want to have a mobile communicator/computer, and want one with a screen and all-day battery life.

Well before the iPhone flew off the shelf, using the the previously established smartphones I never had to settle for less than a week of battery life.

Plus anybody could just slap in another spare battery whenever they wanted to, whether they were off the grid for an extended period or not.

Never thought it was going to end, only get better not worse.

Perhaps, but it still amazes me that something like an iPhone with a GHz processor blasting pixels to the screen all day, can run on a wafer thin battery (Mr. Creosote reference for the cognoscenti) for a full day.

Given that humans sleep at night, recharging the phone at night is a reasonable price to pay for the benefit of a smartphone vs flip phone, but a device that needed charging during the day as well (e.g. due to a form factor with a tiny battery) would almost certainly be a product killer.
