Corning imagines "A Day Made of Glass":
Pretty cool video, but not very plausible in my opinion. The video mostly just extrapolates modern touch interfaces and applications onto giant pieces of magic glass -- essentially turning every surface into an iPad. I think it's much more likely that future displays will take forms like Google Glass or networked contact lenses. We'll each be immersed in our own personal augmented realities and there will be no need for giant pieces of glass everywhere (much to Corning's dismay, I'm sure).
What's more... touch interfaces? Puh-lease. Fine for browsing the web or playing casual games, but terrible for almost anything else.
