The whole system.. from the sizing of the borders and titlebars to the font and the menu density to the icon sizing, spacing, and design in general...
All feels more coherent than anything today. It feels like it was sketched out by a small group of people and executed incredibly well. Meanwhile things today look more disjointed like the product of a lot of design-by-committee.
Susan Kare's 'Chicago' in this rendering hits hard in the nostalgia factor to me a well.
I'll be that guy... the system font for menus, etc in OS 8 and 9 is "Geneva" [EDIT: It's "Charcoal", of course. Thanks for the heads up!]. It was "Chicago" up to and including System 7.x.
iPod used Chicago for the same reason Chicago was used on the original Mac—it was designed to make UI elements clearly readable on low resolution monochrome screens.
I agree it was a high point for UI/UX logic. The filesystem was part of the OS experience and it generally made sense with little magic going on.
I have wondered in the years since whether the newer abstractions and UI patterns we find in MacOS and Windows are actually necessary. These days both OSes are trying to be tablet friendly, trying to discourage user-installed/curated software, and trying to promote bundled cloud services, so it's not even clear to me whether the MacOS 9 abstractions are really the correct ones anymore, as evidenced by the many problems with cloud backed file explorer interfaces, synchronization, etc.
