The flush charcoal version is definitely my favorite so far. I'd rather have one big silver knob as on the current models though rather than a little fingerwheel design as on the flush. I also have no problem with the small buttons on my 1070. Something I particularly like about the current models are the panels used for front inputs. They're set up in a way that I only have to expose as much as I need unlike your larger panel. Putting USB on the front though is a great idea. Being able to just plug right in from the front for updates would be much more convenient (I still haven't updated to the no-audio fix because I can't be bothered to pull it out and drag it around and my girlfriend's laptop doesn't have an RS-232 port).

I really like the current design a lot. The only problem that needs fixing is the screen: it's practically unreadable at any distance greater than a foot.
