Summary: The great thing about these devices is the "Unifying Receiver" that fits into your computer's USB port. I'm typing this on a keyboard that uses the same receiver as the mouse. I would also recommend downloading the set point device management software from Logitech, but it is not necessary.
Summary: This mouse is a "must" to have with any computer, especially a laptop. The mouse is a little smaller than traditional ones are. It has a good tactile feel and is extremely responsive. You get used to it fast, although it is a lot quicker than the old corded mice were. A good side to it is that it seems to work on almost anything. I have mine on a bare slide out drawer, and frequently use it on the couch.
