I paired my Logitech MX 900 BT mouse with my 12" PB and 12" iBook. Both worked as well as I can expect, given the fact Logitech does not provide the control center for Macintosh. The beauty of BT is a standardized connectivity as long as your machine has BT. Battery life for MX900 is less than what I get from MX 1000 Laser Mouse (which is a standard bearer in the world of mice), though.
