I'm currently using a X1 Carbon in office, got it in last year's July. Everything is perfect (for me) with this laptop, as I was provided with HP Elitebook and Dell XPS in the past, I think X1C just nails it. Its built and also performance are top notch.

However, something is bugging me though. I see some little spots like water spots on the laptop and I have to use wet tissue to wipe them off. Fortunately, they can be wiped off but after a while, they will come back. My colleague who's using the same model as mine doesn't have such issue with her unit. It's quite annoying for me because they are obvious at certain angles. Is it due to the air? Too humid? Maybe not, I'm sitting right under the aircond and it blows straight to me. Should be too dry right? So any clue? Or lemon unit and plain unlucky for me? I can snap photos to show but that has to be tomorrow as I don't have it now because lazy to bring back the laptop.
