Pros:Looks and feels great, glides nice on mousepad.
Cons:Everything about using it on a Mac, go Microsoft.
I am using this on Mac OS X 10.4 on a PowerBook. The mouse feels and looks nice. Other than that I have had a lot of trouble with it. Every time I start my computer I have to re-adjust the pointer speed as it is so fast it is useless. Sometimes it just doesn't work and I have to re-start and re-instert the reciever, trying both USB ports to get it to work. Also no software is included for Mac which is unacceptable. Windows software is included, I'm sure there is room on the disk for the Mac version. This is the third Logitech wireless I have had trouble and it will be the last. Microsoft mice are superior, and I like nothing about Microsoft.
