I've been super happy with my Surface Pro 3, that is until this week when I noticed that it is severely warping.

This is not the kickstand and it is not the keyboard. The whole back of the device is pulling in towards to front (screen side) like a banana. It is starting to get very noticeable from the top where the power button is. It is noticeable but less severe at the bottom by the keyboard. I am very careful with the device, and carry it in a huge laptop bag with no other contents.

Is this a known problem? i couldn't find it reported anywhere else. I am currently suspecting heat warping, as I think the hotter components are at the top.

This is the i5 version.
