I wish they'd go further, though: how much battery life could Apple get out of an iPhone if they kept their great minimization and efficiency-maximization of the electronics going, but pulled back from the thinner-and-lighter-every-time mantra and devoted all the saved space to a bigger battery?

An iPhone that's smaller than my still-pocketable non-Apple phone isn't that appealing to me (yay for having above-average-sized hands!). An iPhone that could go a week easily on a single charge would make me sit up and take notice, though.
