For every tiny, iterative change to an iPhone there is a huge press event. Which is fine if you're into that, but for most of us, we'll get a new phone when we need one and unless the upgrade gives unlimited battery life, it's not going to change our day-to-day life.
That's why I love it when people share these small little innovations they've discovered that could actually make a difference. Sometimes that difference is small, sure, but it's measurable and for some people, life-changing.
