Advantages: It has a good mouse. The fact that she is a laser is undeniably advantageous. Prior to that, I used mice from Mike's that had a blue diode, and I did not enjoy using them. It's wonderful because there are a lot of add-ons that can be customized. Its cons: The most significant disadvantage is the cord, but obviously the author has never used a regular wireless mouse. The form is not one that works for me. However, these are only very minor concerns.
