Apple is touting Safari 4 as the fastest browser on the Web for both Windows and Mac. Depending on your computer's specs, that may indeed be true. However, if you need more than speed, Safari may not be the best choice. It's zippy with the JavaScript, but on Windows machines it still consumes a huge amount of RAM and still doesn't support extensions--something the Mac version can do.

What it does offer, though, is a uniquely visual browser right out of the box. Top Sites and Cover Flow for History and Bookmark browsing will either entice or annoy, but there's no doubt that Apple is finally taking its browser seriously.
