I also returned my SP3, keyboard, office, warranty and case. Funny thing is, I used 400+ dollars in giftcards for the trade in any game and get 10 dollars, up to $50 per transaction. The day after I initially bought my SP3 I had a dead pixel, I took it into the store and swapped it out and they also had the bundle deal (type cover, office, case, extended warranty) for 199 or something. Since I already purchased the typecover on launch day, they had to return everything and recharge me in order to get the bundle to work. Well when I took back and returned everything they had to give me back the 400+ dollars as credit rather than in giftcards because of how they returned and recharged me. So it worked out in my behalf!!!! I was happy. Got back 1800 bucks rather than 1300 and 400 in giftcards.
I ended up purchasing a Macbook Pro as I needed a machine that sliced through Premiere, After Effects. I upgraded to an i7 processor and upgraded to 16GB of ram in my Macbook Pro.
I liked the SP3 if I only needed it for light work and internet browsing. But it overheated a lot, the windows store is laughable and pretty bad, and isn't fully supported by many of the standard applications out there! And if there is an app out there, the design is atrocious! I liked how thin the surface was and how light it was, but again, I need a portable device that I can do some major work on! The surface pro just didn't do it for me. I rarely used the Pen when I thought it would be one thing I would use a lot as I write movies. I rarely used the device in tablet mode as the apps weren't great. I just didn't feel like a 1700 dollar machine to use for basic stuff was worth it.
Good luck to all who kept theirs and enjoy it.
