I guess it depends on what Jony Ive has up his sleeve. Hopefully something very special. Right now the iPhone design is unlike anything else and I hope they can replicate that in something newThat won't be necessary when the antenna is placed on the outside borders like the iPhone 4/4S.
Huh? They kept the same basic design for 3 years, and are on the second iteration of the only real design change...and who know's if they'll keep it going for a 3rd.While I love new innovations, I get really annoyed at the constantly changing shapes of iPods and phones etc. Apple keep on going on about their eco credentials and how their designs use less power, are smaller, utilize better glass and materials etc. But if they're going to keep changing the shape of their devices each time they up the tech inside it, then it just forces us to chuck out all the cases and other third party extras that we've bought along the way. I know apple is all about the lets go naked side of it, but really? would it kill to keep a design current to prevent massive waste as manufacturers dump their obsolete stock and create new cases to fit the new version.
