Beyond the iPhone 5: The future of Apple’s mobile devices →

Great article by Matthew Panzarino on the rumored iPhone and iPad updates, especially regarding the iPod Touch (which I completely ignored in my speculation).
Considering the iPod Touch a bit more thanks to this article, I think my guess is even more likely that the rumored “thinner iPhone” is the low-end model, not the flagship.
One factor I hadn’t thought of when I wrote the speculation post is the camera thickness: it’s pretty difficult to make a device significantly thinner than the iPhone 4 that contains a good camera today.
It’s possible that the next flagship iPhone could be using a significantly thinner camera sensor, but it’s far less likely to happen quickly than other component advances. High-end, variable-focus embedded cameras like the one in the iPhone 4 contain moving parts and need room for a big sensor and some basic optics. The iPhone 4’s is almost the full thickness of the phone.
I love link posts because I don’t feel pressured to write a coherent conclusion.
