My surface pro 2 I just purchased 3 days ago from bestbuy the original unit with the lotnumber of 1351 was very warped. my new unit is just slightly warped but I took it because it was their last surface pro 2 with the newer lot number. Now it seems like the adhesive for the middle of the kickstand never stuck so it looks slightly raised on the middle and doesn't sound like a normal click you would hear when you close it so the outer parts of the kickstand are flush while the middle of the kickstand looks slightly raised by about 1mm. you can feel the difference when you side your finger over that part of the kickstand when its closed. anyone else have that issue?
