I have multiple MacBooks, and also prefer a mouse, despite having an apple magic trackpad. I use a Logitec M720 Triathlon Multi-device Mouse . I can configure it to connect to 3 different bluetooth enabled computers or 2 + 1 Logitec Unity USB Dongle. Using the utility provided by logic, I have set the big side button to open mission control. there are also two small side buttons which can be programmed. I now use more than my trackpad. i can also us a button to allow or disable continuous scrolling. Recommended.
