Ok, so I called the MS yesterday and I was told the usual that it would take a few weeks before it would be returned to them. I mentioned that last time I called, I was told since you shipped it out about a week late, you sent it via next day. And once they confirm the unit, they send it back 2nd day. Its been about two weeks now. He checked the stock room. Came back and said it just came in today. They'll open the unit up and update it for me then call me to come and get it. I said that would be great! I heard they sent me a SP3 because they no longer are making SP2. He said, um I have to check but I thought we were still getting SP2. He checked the box and said it was a new SP3 i5/8GB/256GB SSD. They sent it with a new keyboard and pen and power supply. I said I would come down that day.
So I get there and the guy gets me the SP3 (just the SP3, no box or anything) and had me sign a paper saying I got it. I said, where's everything else? He said, all you turned in was the tablet. I said, I was told not to turn in the keyboard and everything else. And how am I supposed to use the SP3 without everything? It's a different pen, and different power supply and keyboard. He went to the back and came back with a brown box that I assume the surface was in, a bubble wrap that had a pen and another with a power supply, and a new keyboard box with a keyboard in it. He kept the brown box, and gave me the rest and put them in a MS store bag.
So although it took a while and it felt weird the way things was handled, MS really did upgrade my SP2 8GB w/256GB SSD to a SP3 with same specs.
