Yes, I was astonished to see Apple finally did it. Yay! Safari is slowly crawling into 21st century.
Who knows, maybe one day I'll start using Safari myself (which I currently only do for occasional testing).
Note: No offense to those who love and use Safari. I know these are all personal choices that have many different reasons.
My main remaining obstacle to using Safari now is the behavior of its address/search field. Who knows, maybe one day Apple lets users disable the annoying convulsion/animation of the address field content that occurs every time you place the cursor there. Hey Apple, you know, no other browser does it.
