Apple just released the beta version of Safari 4. I just installed the 26MB download and Safari 4 has a big chance to get me off of Microsoft IE 8. The new Top Sites and Coverflow Browser history are really very sexy to look at and to use.
The pseudo 3D and mirror effects look great and the browser is very fast in displaying the new UI gimmick.
The new Top Sites feature learns your favorite sites from your surfing behavior. I surfed 3 times to I4U News and now it shows in my Top Sites that is prefilled with Apple's picks. Coverflow Browser history works exactly like the twin in iTunes.
There are 150 new features in Safari 4, but the important first impression it makes to me is a very good one. I will use it now instead of IE 8 beta for the rest of the day and see with which browser I find myself starting the day tomorrow.
You can download Safari 4 for Mac and PC here.
