John Gruber, responding to a Bloomberg report that the new iPhones are entering production next month:
[T]o me it makes more sense to see it as a situation where an array of screen sizes to choose from is better than one-size-fits-all. Why not keep the 4-inch size and add a bigger iPhone (or two?). Agreed. Think: MacBook Airs, MacBook Pros, and iMac. As for the rumored new sizes, I'm preemptively leaning towards the 4.7" version. Big for big's sake isn't enough for me, as I also value how pocketable and comfortable my phone is when being used one-handed.
