Any skin has more surface area than the smooth metal surface of the Surface device.
Applying a skin is much different than placing the device under a blanket or in a book bag or rubber case while powered on, etc.
These provide an air gap, a thermal insulator. Like a coat. Separates warmer from cooler.
Skins do not provide an air gap. They become part of the unit.
With the pen stand on the tablet, would i be able to close the tablet with keyboard? Also when you remove the skin , does it leave any glue on the surface tablet? Thank you.
