Hi, So I broke my bank account and ordered a 15-inch MBP Retina. I'm not much of a trackpad kind of person so I'm sticking to my mouse. Any recommendations? Price is not a serious issue but obviously the cheaper the better. It would be AWESOME if it didn't take one of my USB ports as the MBP has only two. Is there a mouse that can be paired with the laptop without a receiver? I don't want a small mouse. I use a Logitech Performance MX with my desktop and I'm happy with that but just want something different but equally good. Any competitors? Does the Performance MX come in other colors? Awesome if there's a white or silver color! No Apple magic mouse please! Would love to have back-forward buttons on the left side. Any help would be much appreciated.
