@gadgetoid @mntmn I agree with having something included in there for scale (and I even like the lego minifig idea). Other things you might consider including for size comparisons might be, a dvd/blu-ray case, a nintendo switch, a soda can, or perhaps a run-of-the mill paperback novel.
If you think back to the old macbook air reveal, really it was the removal from the manilla folder that shocked/impressed everybody. It was impactful because people knew that size.
