Nope, they took the worst aspects of the Logitch G13 and put them into the Orbweaver. Unless you have giant hands you can not reach all 4 rows of keys with out moving your hand. With your hand in a natural position your fingers will rest in the "WASD" position with your middle finger on the center button of the second row. In order to reach the 1st/top row of keys you have to move hand or unnaturally stretch your fingers to reach them. Especially the 01 or 05 keys.
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.
Edit:
They get credit for just one thing, they removed the useless wheel and just gave you a normal button.
