Myke and I talked at length about Apple’s event today, but I thought I’d write out some of my thoughts here.
The obvious news here is the iPhone 5’s bigger screen. At 4 inches and 1136 x 640, the new layout is 16:9 — perfect for movies in landscape, and no wider. Apps that don’t scale or fit will be letterboxed at the top and bottom.
While I know very little about app development, from the people I’ve spoken to today, moving to this new screen shouldn’t be nearly as much work as going to Retina was. In short, Apple changed the physical screen size of the iPhone in the easiest possible way.
