New Safari 4 beta is presented on Mac and Windows platforms, how we all know Saffari is good and nice design Web Browser, i like its design! New Saffari eat lot of MB from RAM, about 350MB when opened 10 tabs, its more than Firefox, Firefox on my PC eat about 200MB.  If you used Opera or Chrome, Saffari will be easier and more beautiful and it will be awesome. On Windows platforms it is awesome. Speed is actually not incredibly important in a way—loading sites like ESPN, the New York Times and Slate against Firefox 3.0.6 and Chrome 1.0.154, honestly, they're all pretty damn quick, averaging around 3 seconds, though on super-Javascript heavy pages Safari 4 and Chrome, both based on Webkit, perceptibly edge out Firefox. New Saffari is fast. . Windows UI elements—which seemed especially dicky in a way, given how anal Apple can be about standardized UI themselves—Apple is actually playing nice. I think it's a lot more Windows-friendly than the initial Windows versions of Safari, and its excellent performance (You need at least 2gb RAM for feel the speed of Saffari). Technics and Gadgets blog thinks this is best browser which is now aviable!
