> "I just wish ... what’s here felt even half as adventurous as what’s happening on the iPad."

I don't.

I don't want my desktop to feel adventurous, not even half-adventurous. I want it to be an efficient tool for getting the job done.

Please, desktop OS-manufacturers, resist the lure of adventuring new bells and whistles, and invest that time optimising, smoothing corners and making everything more efficient.
