Just purchased a mamba mouse last week and got caught up in this idiotic "benefit" of having to register online and install Synapse 2.0 to install a mouse driver. Seriously? I can't believe this is being touted as a Service and of benefit to me. I see it as yet another way for a vendor to over use "the cloud" to get closer to their customer's machines and usage habits. It's product marketing gone bad. Way to go Razer!
