There are 17 [!] screws holding the front panel to the magnesium framework.

We didn't explicitly test the metallurgical nature of the framework, but we are pretty sure it's magnesium.

After a little bit of prying, the front panel separates from the rest of the display assembly -- a refreshing change from some other popular devices. Although to be completely fair, Apple's iPad also doesn't have an LCD fused to the front glass.
