Hi, It took Microsoft 2 weeks to ship me out a new Surface. I just want to make sure my new one is in better condition than my old one. Does anyone have any advice in terms of tests I can preform to both units to make sure that the new one is infact in better condition? Sadly (although I don't care much), the one they sent me is using the old processor and has a smaller serial no. compared to my other Surface (funny how it took them 2 weeks to find one for me at all...). I'm fairly sure they've lied to me and sent me a refurbished unit. One thing I've noticed is that the colours on the screen are different.
