I'm seeing the same sort of wear you guys are on the corners of the screen and tablet. Also seeing the same kind of wear in a semi circle around the screen pivot and some random marks on the top of the lid. These are fairly minor cosmetic blemishes. The main issues are the fingerprint reader, the touchpad, and the main battery. The fingerprint reader has never worked right and one of the panels fell off within 5 days of getting it. The touchpad has also always had problems and frequently the cursor gets stuck on some invisible vertical axis. This isnt as big a problem since I have disabled it and usually use the pen anyway. The battery wear (72% wear on my second battery) has been well documented and probably doesnt need any explaining since I'm sure most people have experienced it. It is odd though because my modular battery has no wear at all.
