Now, I'm pulling from memory, but wasn't there something recently about Gorilla Glass 2 being equally strong @ .8mm thinner than 'normal' Gorilla Glass? That would be a heck of a coincidence now, wouldn't it?
Same over-all thickness, with the thinner (but equal strength) glass allowing more room for the internals?
I was thinking this but doesnt the face and glass rest inside the thicker shell? The glass will be a factor. I can see this getting to within 0.5mm of the iPad 2 though
