While I love my Logitech MX 518 to death, I'm wanting to try out something different. While I've not typically had good luck with Razer peripherals, much of that came down to software - buggy drivers on both the Mac and Windows side. The 2013 version of the Orochi looks promising, but user reports of Synapse 2.0 have been mixed at best. Putting aside any discussion of "Mouse DRM" is Synapse 2.0 at least functional and able to keep things in sync between Windows and OS X? In all honesty, I wish Logitech would its own version of the Orochi, basically something like the G700 only smaller.
