Apple has just released Safari 4 Beta for Windows and OS X, and it sure is amazing, to say the least. If Google Chrome blew you away, be prepared for the onslaught of features by the new Safari 4 Beta. Featuring a blazing fast new Nitro JavaScript Engine on Webkit and with an Acid3 score of 100, it’ll knock your socks off.
Top Sites shows you up to 24 recently viewed or most visited web pages. It does so in a very cool 3D grid.
Cover Flow. That’s right, the very loveable cover flow has found its way into browsing as well now, letting you go through history and bookmarks at a glance.
From a testing perspective, this is one of the fastest browsers we’ve laid our hands on. Although it seems to have totally ripped off Chrome, but then Chrome itself is Open Source, and Google would be more than happy to realize that it inspired other browsers. Which was one of the goals for which Chrome was developed. It is also very stable for a Beta, and the features are just mind blowing and keep you immersed in your websites. A must have if you want better browsing than what IE and Firefox offer! For the full list of 150 features visit here.

Boy oh boy.
I haven’t used it much, but I think I like what I saw :)
This article took the words outta my mouth. Except for one thing – the beta is HELLA unstable. It crashes when closing some tabs, and sometimes it crashes just randomly. I’m still OK with it, I’m in love with this browser.
