I'm about 90% sure that I am going to be upgrading to a blackbook from a dell within the next couple of days, and have a question about a mouse. Right now I use a Microsoft Wirelesss Notebook Optical Mouse 3000, and actually like it a lot. I've read enough bad reviews of the mighty mouse to disuade me buying it, but I really like the idea of having the side buttons to use for expose or dashboard. It'll be nice to take full advantage of my new and improved computer. I'm just wondering what a good mouse would be? Bluetooth would be nice, but not essential. I'm looking for something with the side buttons, or some other way of accessing expose from the mouse. I really know next to nothing about mice...I've never really put much thought into it before. Thanks in advance for all the help.
