Looking at the way many of the apps have so much white space I think it's
inevitable that we are going to see a 4+ inch display next year.
Much of what iOS 7 looks like does resemble Android at least in this text regard and
one of the reasons why Android does it because it makes it easier to translate apps to
different sized displays.
Looking forward to fall and getting updates to iOS and OS X and hopefully Aperture and iLife as well.
