I must admit that I was not familiar with Safari so far, and that the clean and sleek aspect of this browser surprised me. There are no toolbars or other add-ons to mess with the clear look; only sites thumbnails lined with accuracy. At only one glance you can observe all different web pages. Once you start browsing the web, Safari begins to memorize web sites; the most visited will be placed above the others, as your Top Sites. You can add or unpin thumbnail windows out of the browser. When selecting an image, the site will maximize on the screen; you can choose to browse sites also in full screen. I managed to add a bunch of my favorite web sites, but I could not find a way to scroll down the browser to see them too.
The minimalistic toolbar has by default a history item, which opens your latest activity in sliding windows, and a reading list item, where you can save links to read later. You can customize the toolbar by adding other items that you prefer.
Safaris have also some extensions, such as Twitter or A Better Facebook, but are few. So I expect some further improvements. Safari remains though the browser that has the looks.
