I have literally two dozen little square iPhone chargers, no problems. The new one that came with my most recent iphone... just stopped working. If that's the quality of the chargers now, just skip it. And I certainly don't need a tenth pair of wired earbuds that I can only use on my iPhone.The majority will win, because they will already have an iPhone charger and that way they won't be paying more for the new iPhones (since the more expensive production will be compensated with fewer accessories). You're also helping the environment.
For those who don't have an Apple charger, it will be a bummer.
Still, I think you should have the option to have these items included, if you're going to keep using proprietary ports.
