I picked up an Apple Mighty Mouse from CompUSA a couple of weeks ago. I absolutely love it. Right click / left click is built in and works like a charm, but there are no buttons. Very smooth.
The scroll tip is tiny and beats those scroll wheels. The only negative thing about it is that it is USB. I wish it were Bluetooth.
Other than that, it makes for a very nice portable mouse.
