I have a dilemma here. I need a mouse. I just returned a M.O.U.S.9 from Mad Catz as it's crap. Ironically, I can only get the bluetooth connection to work in OS X and not in Windows 7 and the only way to get anything but 3 button basic operation from the mouse is to plug in the optional dongle. In fact, the dongle is the only way to get it to connect in Windows 7 and I wanted a bluetooth so that I wasn't taking up one of the only two USB ports on my 15" rMBP. So the dilemma here is what mouse should I go with? If I'm going to have to take up a wireless port, should I go ahead and use a wireless mouse? I want something with more than 3 buttons. I have a Razer Naga for my desktop usage and love it. The wireless Naga has a charging station that acts as receiver, so there's no small dongle for it. Plus, reviews state that the connection is finnicky. If I had to deal with that mess anyways, why not just go with the wired version? Does anyone here use a wired mouse with your laptops? How do you manage the cables? Is there anything else out there that's wireless and would fit the bill of what I need?
