Surface seems little bended?

Interesting. I wonder how they producing the case. If they are machining it, then they have a fixturing problem, since if a piece of junk milling machine is going to hold better flatness than I'm seeing. I don't believe there is anything wrong with mine, like I don't believe it's cracked. The manufacturing engineer in me just want to know more about how our Surfaces are made.

I think it's just normal product variation. I put a straightedge on mine. From side to side at the top by the camera, mine is just ever so slightly convex. At the middle just at the joint to the stand, it's straight

If you notice, at least on mine I can see bent reflections in the glass on the front near the bottom also, near the windows button.

I agree, this isn't part of a space-shuttle, so there is no need for an absolutely flat, well uh... Surface. If the variation is almost imperceptible and you have to go through the effort of finding absolutely flat surfaces and edges to check with then it is close enough in tolerance to be used as a tablet, which after all is what it is. I suspect if you checked almost any mass produced item this thoroughly you would find the same thing.

I agree that the variation is probably reasonable for a tablet, but at the same time if mine was convex instead of concave, I would be annoyed by the rocking. Just makes me curious on how it's made.

Yes, convex could be a problem Fortunately it seems the variation is only towards concave. Though I don't know the specifics of the process it is known that MS is using a a vapor MG casting process. In my mind that means sort of like a traditional casting but the material is deposited in the mold as a vapor rather than a liquid. Of course that is just my imagination but it sounds reasonable

The variation would male sense for a casting process. I believe that the Magnesium is vapor and cold quickly to improve the material strength during the casting process.

Sorry of topic?

Always a possibility, but then both sides of the ruler are equally curved.
