That was the beauty of choice, Vista and 7 had two other style for those who hated glass: basic and classic. You were not forced to shut up and put up with itI was thinking the same - from that animation it could be more 'Aqua 2.0' than the dull grey of VisionOS. I'm a little worried about legibility though. Dare I say Microsoft tried to go full-glass with Vista and quickly regretted it. Hopefully Apple learnt some lessons from their failures.
