Microsoft’s original Surface Pro isn’t even a year old yet, but it has been superseded by the Surface Pro 2. It appears that Best Buy still has some stock of the original model that it wants to move this weekend. Weve seen some price reductions on the Surface Pro before — including cuts following the Surface Pro 2 release — but Best Buy is offering a massive $400 discount on the original retail price, bringing the Surface Pro down to just $499.99.
