This wireless mouse is rechargeable and includes a charging base. The mouse also has shortcut buttons for Windows Vista. As with the 6000, when you accelerate the mouse pointer with the Microsoft Wireless Laser Mouse 7000 via the software you give up some accuracy for the sake of smaller hand movements. The scroll wheel is smooth scrolling and lacks any click. This makes it easier to scroll long pages by flicking the scroll wheel. However, I found that I hit the scroll wheel often be accident making the page jump around a bit.
