Safari is the world’s fastest and easiest-to-use web browser for Windows PCs and Macs. Safari is the fastest browser running on Windows, based on the industry standard iBench tests, rendering web pages up to twice as fast as IE 7 and up to 1.7 times faster than Firefox 2. Safari joins iTunes in delivering Apple’s legendary user experience to both Windows and Mac users as well as full support of open Internet standards. Safari features easy-to-manage bookmarks, effortless browsing with easy-to-organize tabs and a built-in RSS reader to quickly scan the latest news and information.

“We think Windows users are going to be really impressed when they see how fast and intuitive web browsing can be with Safari,” said Steve Jobs, Apple’s CEO. “Hundreds of millions of Windows users already use iTunes, and we look forward to turning them on to Safari’s superior browsing experience too.”

Safari has always been the fastest browser on the Mac and now it’s the fastest browser on Windows, loading and drawing web pages up to twice as fast as Microsoft Internet Explorer 7 and up to 1.7 times faster than Mozilla Firefox 2. The speed of Safari combined with its intuitive user interface lets users spend more time surfing the web and less time waiting for pages to load. Other Safari features now available to Windows users include SnapBack, one-click access to an initial search query; resizable text fields; and private browsing to ensure that information about an individual’s browsing history isn’t stored.

Safari supports all modern Internet standards so users can view websites as they were meant to be seen, including HTML, CSS, JavaScript, SVG and Java. Safari software updates are delivered seamlessly through Apple’s Software Update application, which automatically checks for updates.

Safari v4 is finally here and supports many new technologies. Browser your favourite websites (or your browsing history) in 'cover flow' mode, quickly search through your web history, support for the latest web standards such as HTML 5, a flawless ACID3 test, as well as being far faster and shipping with a Windows look-and-feel.
