I have a K480, and while it's more-compact than a full-height keyboard, my guess is that he's got a mechanical keyboard there. The rubber-dome keyswitches on the K480 aren't as nice (at least in my opinion; people have different views on what they like in a keyboard). It sounds like the K780 is a rubber-dome as well.
I do agree that having some kind of stand is handy, but if you have anything that you can lean a phone against
doesn't take much
that'll also work, at least on a desk or table.
