They also took away the d-pad/joy-stick combo and made it just a joy-stick. On the Nostromo you can remove the joy-stick and just use the d-pad as extra single press buttons. So it works for keybinds like any other key on the device does. Trying to use it as a joy-stick is almost impossible to be that precise with your thumb. You can never use it to replace your mouse.
The G13 suffers from exactly those same problems. The Orbweaver is beyond pointless.
They get credit for just one thing, they removed the useless wheel and just gave you a normal button.
