If you use Boot Camp to dual boot, you will quickly become frustrated with this mouse. In Windows, just getting it connected is not simple. The typical method of pairing in Windows won't work and you have to go through a convoluted exercise to get it to pair. Once paired, there is significant and random lag in the input. When used with programs like AutoCAD, or Photoshop, you will probably want to throw this mouse against the wall.
Under OS X the mouse performs much better. It doesn't suffer from the same lag problem or connectivity problems. The performance with AutoCAD in OS X is acceptable but not quite as good as with a typical mouse, like the Logitech Anywhere MX. Tracking under OS X is much better and the mouse feels much more connected and responsive.
The construction of the mouse feels flimsy and hardly worth the amount they are charging. By contrast, the aforementioned MX mouse feels solid and has some weight to it. Battery life seems okay but less than the Unified receiver variants.
If you are evaluating this mouse because you want to free up a USB port on your MacBook Pro, I'd recommend looking for a compact USB hub instead. I would not recommend this mouse to anyone who needs to dual boot and I would still recommend the MX over this mouse even without that consideration. This mouse would only be good for those who insist on freeing up a USB port and use OS X exclusively. In that light, it would be worth the trouble but you will pay a premium for that convenience.
