If you've been on the fence about purchasing one of Microsoft's Surface tablets, now might be the time to pull the trigger. That's because Best Buy has slashed $400 off the price of the original Surface Pro but the deal only lasts through Saturday.

Launched less than a year ago, the first generation Surface Pro 75  is still a solid machine - especially at this price point. It comes equipped with a 10.6-inch, 10-point capacitive multi-touch LCD operating at a resolution of 1,920 x 1,080, a dual-core Intel Core i5-3317U Ivy Bridge processor clocked at 1.7GHz, 4GB of RAM and 128GB of flash storage.

Other noteworthy features include Bluetooth 4.0, a microSDXC card slot and 802.11 a/b/g/n wireless. The slate measures 13.5mm thick (0.53 inches) and weighs two pounds.

It would seem that Best Buy is looking to clear out old inventory to make way for the new Surface Pro 2 79 which hit store shelves late last year. Aside from being a bit lighter and having a faster / more efficient processor and an adjustable kickstand, the two systems really aren't very different at all... except in terms of price. A Surface Pro 2 with 128GB of storage will currently set you back $999.

The offer, which brings the total cost of ownership down to just $499.99, is good at Best Buy retail locations and online. It's the cheapest price we've seen yet for the Surface Pro, a fact that could very well hold true for the foreseeable future.
