I’m not really that amazed by it. They do the deceptive marketing trick of taking photos at that angle…by that definition if you look at me from the back I have a 6 pack and chiseled abs, until you rotate around and see my beer belly.
Thinness is great on mobile devices, but on something that sits on a desk with a stand, the footprint is defined by that bounding box so you don’t get any real benefit other than it being slightly cooler than the last generation.
