Microsoft's next-generation web browser, Internet Explorer 8, has arrived. In a surprising move, after the demo of IE8 and its new features at today's session of the MIX08 conference, the startling announcement was made: "It's available for download now". The new browser showcases many new features and improvements, like Facebook and eBay integration, standards compliance, and the ability to work with AJAX web pages. What's most notable about IE8, though, is more than a sum of its parts. If anything, this launch shows that Microsoft is not taking Firefox's creep into browser market share lightly.
