When I first installed the beta version I admit I was a bit taken aback by the new Tabs On Top feature. It was weird and I didn't like it in the beginning, plus sometimes I mistakenly minimized the window when clicking on a tab. But after a few days I eventually acknowledged that it was useful, because it takes advantage of the otherwise pretty useless top bar and I have more space in the actual window.

Just when I'd begun to love said feature, they removed it!! I tried the normal version, but I'm annoyed at the lack of Tabs On Top... So much that I'm sticking to the beta version, since it hasn't given me any problems at all. I understand that new users, or people who are used to the previous versions, won't like it in the beginning, but I think it's just a matter of getting used to it (like it happened when the OS shifted from Classic to OSX, in fact).

I think Apple should at least leave the choice to users, for instance by inserting a feature that allows you to choose between normal tabs or tabs on top!

Anyway, except for this, I'm totally satisfied with the new Safari. It's faster than the previous version and it's also lighter. I tend to leave the browser open for weeks, and the previous Safari became progressively slower, while this one still feels fresh after more than one week.
