Mice - Wired or Wireless

What mouse you want to use depends on your preferences and weighing the pros and cons of each.

Wired - The pros are that wired mice are reliable. Unless the cord gets pinched up or partially unplugged, it works very well. Another pro is that you will never have to be concerned about batteries. The cons are the cord. They are subject to damaged and sometimes length limitations. The sometimes snag on other cables as well.

Wireless - The pros are that there is no cord. Well, not for the mouse anyway. Unless the system comes with the wireless controller built in, you will have a base that plugs into your PC. From there to your mouse it becomes wireless. You should have a better range for the wireless since you will not have limitations of a cord. The cons are batteries. They usually last a while, but eventually need to be changed. Synchronizing the signal can sometimes be an issue (depending on manufacturer). I have also seen where one mouse controlled two nearby PCs at once because they happened to use the same frequency. Doesn't happen too often though.

Personally, I prefer wired mouse that has an optical sensor instead of the old fashioned ball in the middle. The ones with the ball pick up too much lint and cause the mouse to not be as smooth.
