The first Microsoft Intellimouse dates all the way back to 1996. Backed by a remarkable track record, the Intellimouse brought us many innovations that included the incorporation of a scroll wheel, optical sensor, and auxiliary buttons. A wireless model was also released to the public. Despite its popularity, Microsoft eventually discontinued the product in 2012. And now, five years later, the company announced the latest iteration to the series, the Classic Intellimouse, at their recent Surface Book 2 launch event.Nostalgia is strong on the Classic Intellimouse. It clearly borrows a lot of the design elements from the original Intellimouse Explorer 3.0. The ergonomic design is completemented perfectly by a clean, black and grey theme. The red tail light has been changed in favor of a white color to make the mouse look sleeker than ever. There are five buttons on the Classic Intellimouse's body, and three of them are user-customizable. A new 3200 DPI sensor is also hidden in its interior. With the help of Microsoft's BlueTrack technology, precise tracking is possible even on glass surfaces. The mouse's report rate is impressive as well coming in at 1000 reports per second. The Classic connects to the computer through a standard wired USB 2.0 connection.Most windows users won't have to worry about compatibility, since the Classic Intellimouse works fine in Windows 7, 8, 8.1 and 10 environments. Windows 10 S users won't be able to customize the three programmable buttons though. As for Apple Mac users, I'm sorry, you're out of luck on this one.Microsoft has put the Classic Intellimouse up on sale for $39.99 at their online store
