Hello all, I have an i7 SP3 with some hardware issues. In the past I have just driven the 90 minutes to a Microsoft Store because I've not really had any experience with the MyService Surface warranty site. Is there anyone here who has done the "Advanced Exchange" on their site? I'd like to know if they send out referb units or is it the still factory sealed new unit like the do in the stores? Thanks for any guidance on the matter.
