What makes this mouse unique is that it has what Logitech calls Darkfield Laser Tracking. This feature enables it to track on glass. How often someone mouses on their windshield is uncertain, however. The mouse is advertised to work anywhere, on anything, and with anything. Anywhere MX works with old and new systems from Windows XP through Vista – if anyone is still using this failed operating system – to Windows 7, 8 and RT. Mac compatibility wasn’t overlooked in the design either. The Unifying receiver connects up to 6 compatible devices. Logitech offers several wireless Unifying mouse choices from $29.99 to the top Performance MX
