I have spent everyday since I bought the surface book on Oct 26 either on the phone with Microsoft support or my IT department. I even drove 200 miles to from my home to have my IT department work on it. Still can't hook up a portable monitor, still can't use dual monitors, battery dies when you close the lid, office crashes All the time, etc, etc etc........I am looking at the device now. It won't even turn on. WTH Microsoft....major fail....I am ok with first product bugs....but not being able to even use the damn thing. I just loaded windows on my mac, and it works....yep windows on a mac works better than windows on Microsoft hardware. I leaving and I will not be returning. Heading to the Microsoft store to return the SB.
