No sign of it and I looked. I'm back to SP2 because of pen issues. I miss the i7 though. It was inexplicably quick, bigger difference than I thought. I had it for almost the 14 days.
Thanks for your clarification. I think we need to know from someone who has it for more than 14 days if the yellowish problem is developed. The issue may not get noticed for the first few days, even I didn't notice it when I first received it.
