+100! I need something portable that only has to handle 4-8 choir/solo mics, and if that existed in the form factor of e.g. the Yamaha DM3, but with the Series iii's multitrack SD card recording, I'd definitely get that! And as you mentioned, in the era of digital stage boxes, there's no need for the console to be larger simply to accommodate more analog inputs. Even more so given the Series iii's User page which means you can have exactly the faders you need and no more all on the same page, even if there were only, say, 9 physical faders. Add a large touch screen with a few contextual knobs & buttons, and you really don't need a large control surface to get a lot done quickly.
