Safari 4 public beta released!!!!

It works great, stable, and most importantly, it's fast.

I like the location of the new tab bar, which it saves some pixels so that I can read (a little bit) more at a time on my 13" MacBook.
One complaint is that now, the double-tab to open a new tab is no longer available. Instead, it restricts you to press on the top right corner.

Anyhow, overall, it works great. And so far, I love it.
