I for one use an iPhone BECAUSE of its smaller form factor, so I hope Apple doesn't go along with this trend. I don't need a phone the size of my head. I've done the 4.6-4.7" phone thing with a Galaxy Nexus and a Nexus 4, and both are just too damn big for a phone. If I want a screen that large for a video or whatever, that's when I get out a tablet.
