I agree that it isn't as big a deal as some people are making out. But at the end of the day you can't disagree that it was a massive flaw from the beginning of the iPhone (and its days before it let people develop apps for it) driven likely by the megalomaniac supposition that if you build a phone you can't reach all parts with from your thumb: "no one's going to buy that."*
