If this design looks old school to some readers, that's because it is. In 2009, Apple introduced a feature called "Tabs on Top" in the beta version of Safari 4, which was similar to their implementation here. Needless to say, people were horrified — horrified — that Apple would dare amend the sacredness of their UI. Walt Mossberg called it "Apple's worst decision." Mac Daily News refused to even use them:
WHERE THEY BELONG. And Mac Observer was just totally confused:
Chrome introduced a similar layout around the same time and has used it ever since. SHOCKINGLY, no subsequent reports were made of Chrome users not knowing where or how to drag their windows for the last 12 years. Anyway, when the GM shipped, feature was noticeably absent and Apple said no more about it.
Personally, I have used Chrome ever since, largely because it was faster (at the time), but also because their tab layout is more intuitive. (It most closely mirrors real life when physical tabs are, you know, at the top where they belong. But I may give Safari another go now that Apple has seemingly overcome their fear of Walt Mossberg.
