Anyone know if a 2 button mouse is in development or on the agenda for Apple anytime soon? I love the sensitivity of my Apple pro mouse, but would prefer a 2 button mouse for playing games. I'm just wondering whether or not to hold out for an Apple 2 button mouse (if one is in the making) or just go out and buy a 3rd party mouse (if there's no such thing in the foreseeable future for Apple). Any recommendations for a 3rd party brand? Thanks.
