Huh? What merd!
How does making the edges thinner make it wider and taller?
At the thickest point the MacBook Air is 2cm thick. The while the MacBook is fractionally thicker at 2.75cm. But the MBA *feels* dramatically thinner because of a shell that gradually tapers from thin edges to the thickest point. Instead of a nasty kerb, there is a gentle wheelchair-friendly ramp.
This same profile will inform the design of the new phone. Apple could afford to ship a phone with a larger battery and a greater overall thickness, if that phone came with an MBA-style tapering design. Perception of bulk is far more important than actual volume. That ramp will let it slip into your pocket.
And that design feature is visible in all of the entirely consistent leaked photos. Looks nice too.
Furthermore I am pretty convinced by the middle image in the last row. The shell is lacking the guts - which allows us to see the back of the case from the inside. There are a bunch of what appear to be antenna connectors all over this surface.
I think they are increasing the physical size of the antenna. And have managed to do so while also losing the ugly black-plastic antenna window. This new design has a single continuous surface.
