Yes, it does allow right-click. Though there is no visible buttons in the mouse, any tap on the top right portion of the mouse should trigger right-click. I believe you have to enable this via the mouse settings panel.
Ahh! Very good! Thank-you kindly for the information; I figured it wise to ask before investing ~$70 for a mouse! :-) I'm a PC convert and loving 99% of what MAC can do, the right click thing though was a "must have." Please have a wonderful day!
