Windows 3.1 didn't have any use for a two-button mouse. The second button didn't do anything in most applications.
FYI logitech bluetooth mice are incompatible with Macs. Theyll function, but only as a generic apple mouse (right click and scrolling will still work). Youll only be able to assign expose/dashboard functions to the extra buttons through the expose shortcut settings. The logtech drivers that allow you to fully customize the mouse wont work with them.
Logitech mice are completely compatible with Macs now, you can even download the software from Logitech to make your mouse completely functional with OS X if you haven't done so already: http://www.logitech.com/index.cfm/support_downloads/downloads/mice/&cl=us,en.
You can also download GamePad Companion which will allow the Logitech mouse (VX Revolution etc.) more functionality in games.
