Just a question, why use a mouse? I know some people are accustomed to it, which is perfectly fine, but I would say definitely try and get accustomed to the shortcut/hotkeys that Chrome OS has to offer and maybe activate a few flags by typing in chrome://flags to your address bar. I've found that by enabling a few flags and using shortcut keys, I can maneuver much faster on the keyboard and track pad than I can with any mouse. Just a suggestion! =)
