razer makes quite a few right handed products. it's a trade off to make it better for 90% and lose some customers. i think in this case it's even more important than with mice. trackpad below keyboard instead of to the side is not so good for gaming.
They should make a keyboard with all the keys on the left side. That way, it won't tempt lefties into using their useless right appendage. [Disclaimer: I'm a lefty, though fairly ambidextrous.]
Maybe it would work better for a leftie. A left-handed person could keep their hand on the mouse and use their other hand for the trackpad interface when needed.
