I see some choices that I like quite a lot.
First, split spacebar. Every keyboard should do this.
Second, Ctrl in the bottom left corner. For people who prefer Ctrl in the Caps Lock position, that's also fine but I put my backspace there because backspace is generally used more frequently than control. However, since I would probably use the other half of the split spacebar for backspace, I'd probably use the caps lock position as an alternate Fn key if it's reprogrammable. I still like control in the left hand corner because of accessibility (it's physically easy to find the key at the extreme bottom left, in the same way people use backspace in the other corner), and because when I'm using Ctrl I'm also often using Shift so I'm moving my hand anyways (if Ctrl was where caps lock is you'd still have to move your hand because Ctrl and Shift are both pinky keys and you don't have two left pinkies so you need to move your hand to use your left ring finger).
Third, I like that there's two shift keys, and that the right shift is where it should be rather than shift and Fn1 being switched. Some people don't touch type using both shift keys but I do and consider it a very important feature.
Fourth, the arrow keys are on IJKL rather than HJKL (I'm a Vim user by the way) or HHKB style. IJKL is the resting position for a right hand inverted-T so I consider this a plus. I generally put my arrows on the left-hand resting side, on ESDF (not WASD!), as I prefer that side. I also use ESDF for gaming.
Fifth, I like what they did with Page Up/Down and Home/End rather than making it a six pack. I do something sort of similar, but not quite the same. I put Home where they put PgUp (since home is to the left) and End where the put PgDn (since end is to the right) and then stack PgUp and PgDn on top of each other where they have Home and End.
