(on the right side I've failed to circle the Shift and Control keys which are perhaps the worst part)
The key action is not awesome but is totally acceptable. It would not stop me from using it.
Even in brief testing I could feel that having my hands further apart was pretty cool. Getting your elbows back tucked into your ribs with forearms externally rotated helps reduce the way that normal computer use posture has the weight of the arms collapsing the chest, causing kyphosis.
The fact that it sits flat and is totally old-skool keyboard style is pretty retarded. Who is buying an ergonomic split keyboard that wants a keyboard that could have been made in the 80's ? You need to start from a shape like the MS Natural and *then* cut it in half and split it. You don't start with a keyboard that came on your Packard Bell BBS-hosting 8086 machine. In other words, each half should have a curve and should be lifted and tilted. (the thumbs should be much higher than the pinkies).
(ideally each half should sit on something like a really nice high-friction camera tripod mount, so that you can adjust the tilt to any angle you want; the perfectly-flat or perflect-vertical is no good).
The real absolute no-go killer is the fucking retarded arrow key layout. It's not a fucking laptop (and even on a laptop there's no excuse for that). What are you thinking? There is *one* way to do arrow keys and the pgup/home set, you do not change that. Also cramming the arrows in there makes the shift key too small and puts the right-control in the wrong place. Totally unnaceptable, why are they trying so hard to save on plastic? There should be a normal proper offset arrow key set over on the right side.
And get rid of all those custom-function buttons on the left side. They serve no purpose, and negatively move my left-hand-mouse out further left than it needs to be.
Why is everyone but me so retarded? Why am I not hired to design every product in the world? Clearly no one else is capable. Sheesh.
