alt Hacker NewsVista/Aero 2.0 was purely for aesthetics. Liquid Glass is obviously to enable UIs overlaid on top of uncontrolled content (i.e. camera input from the real world, or be used through fully transparent displays).
Apple really has to bite the bullet somehow here if they want to get everyone over to what they see as the next computing paradigm.
Much like transparent glass tablets in sci Fi movies, this looks pretty cool but I think makes text hard to read and gets old immediately. Is it really a compelling new paradigm?
I think if I had a really improved version of Apple vision I would still want non transparent windows that are clean and easy to read, not floating holograms with glass like distortion?
