HN participants are absolutely part of the target market, but they're innovators/early adopters on the technology adoption curve (which are a small part of the whole market):
https://en.wikipedia.org/wiki/Diffusion_of_innovationsdevices are generally thin enough, so the tradeoff in my mind is between weight and battery life. i'd love true all-day battery life--not the 10-minutes-for-email-20-minutes-of-web-surfing type of "all-day" battery life--where i could have the device on for 8-12 hours doing real work. at the same time i'd love a laptop that weighs a pound and a phone that weighs 2 ounces, with lightning fast processors, huge, bright, high resolution screens, and honkin' graphics power. most folks would easily accept 30%, or even 50%, thicker devices for that.
obviously, that would require like 5X the battery and 3X the weight (made-up numbers). apple knows this already, but the technology just isn't there, so we're where we are with their best compromise. and they're trying to make this better for idevices by switching to wireless power, with the idea being that any time you put down your idevice, you'll be charging it.
