If you have been waiting to get a Surface Pro 4 tablet, and you live in the US, today might be a good day to purchase one. The Microsoft Store site is running a one-day promotion for President's Day that offers buyers of the tablet a free Surface Dock that is normally worth $199.99.

Just a reminder; the Surface Dock connects to the Surface Pro 4 via a magnetic cable, which allows the tablet to connect to external monitors and other accessories via two Mini Display ports, a Gigabit Ethernet port, USB 3.0 ports, and an audio output.

By the way, this special one-day promotion is in addition to a previous $100 temporary price cut on most of Microsoft's Surface Pro 4 models. That promotion won't end until Feb. 27.
