Intense nostalgia. I remember my updating my MacBook from Tiger to Leopard and being inthralled with the new OS welcome video. It was a powerful feeling like a genuine leap was made after rebooting and new powers unlocked. 10.3 used Rokysopp's Eple, and I still love that song and album.
Looking back at the 10.4-10.7 era, I really miss those app icons, they were so easy to tell apart from each other just from shape. The rest of the design language was also a marvel in usability, it was so clear what everything was and how to interact with it.
I really dislike how background audio is locked behind a paywall with the official YouTube app on iOS. Ads I get, but come on, let's not lock away OS features behind a paywall
I think Apple says 11 TFLOPS Single Precision and 22 TFLOPS Half-Precision, which puts the GPU at a Vega 56 I think? I don't think Apple has said how many possible GPU configurations there are, so you could be able to bump it to a 64.
You're correct -- the specs page of the new iMac Pro is intentionally vague, but they do confirm this much at least: https://www.apple.com/imac-pro/specs/
(The 64-variant will actually have 16GB HBM2, instead of 8, though.)
