Vista/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?
All important questions to answer and problems to solve.
It would be interesting if someone had a way to throw a couple hundreds thousand designers and developers into an environment where they have to find solutions so we could get a head start before the relevant hardware goes fully mass-market...
Right, which is why they're pushing the developer community to solve the problem on the iPhone before the next transition to a form factor that's totally dependent on this probably being solved.
