I have a Logitech Anywhere MX mouse and it is great with my Mac. Out of the box, it "just works" to about 95% of what I need. The button on top initiates Expose which is what I want. The "back" button initiates dashboard. I would rather have the back button be, well, back, and the forward button initiate dashboard. To do this I think I need to install the Logitech software - Logitech Control Center. So, my question, is it worth it? I'm kind of a minimalist and prefer to not put software on my computer unless it is absolutely necessary. If the LCC is considered bloat (or even halfway bloat) it won't be worth it to me. So is it?
