x200 tablet multi-touch screen: space between screen layers

[mdjkim]

Let me try to explain: my Thinkpad X200 tablet has the multi-touch screen. I'm able to use the active digitizer or I can tap on the screen with my finger.

Here's what's happening: when I tap on the screen, I see that the top layer of the screen is slightly detached from the layer under it. It almost feels like there is a floating screen protector with a tiny bit of air under it. So, when I tap on the screen, I get tactile feedback because I can actually press on the screen.

Is this a defect in the screen? Or do all the other multi-touch X200 Thinkpads have this same "feature"?
