PC users can't help but notice the similarities between Apple's 'liquid glass' design philosophy and the Aero interface in Microsoft's Windows Vista OS from 2007.

It's hard to look at Apple's new "Liquid Glass" aesthetic and not think about Windows Vista, Microsoft 's much-maligned OS which also touted transparencies and glass-like effects as a bold new vision for computing.

In case you missed it, Apple has caught quite a volley of criticism for what’s perceived as making it seem like Liquid Glass has reinvented the idea of transparency – a glassy, see-through interface – when this was actually done by Microsoft in… yes, you guessed it: Windows Vista.
