I only worked there briefly (I never officially had an office there — Covid times and all that). I don't see it as any different than any of the other Apple campus buildings I worked in (like Infinite Loop) with regard to productivity.

(I've always compared it to some beautiful, modern art gallery — but without any art.)

But to the above degree, I have to say I enjoyed all large Apple work environments (even some of the more far flung ones I worked at like Results Way).

It's because I have enjoyed being able to walk down a hall, up a floor, and chat with The Guy That Works on IOKit Display-support. I am a "social engineer" (not one to socially engineer though if you know what I mean). I truly disliked working from home for extended periods.
