The focus on a unified visual experience that parallels on both computers and tablets, Windows 8 takes its cues from Windows Phone 7.
The big news is that the two versions of Internet Explorer 10 (IE10) contain the same core functionality, but IE10 Metro contains one large difference – a lack of browser plug-ins in favor of HTML5. Not to say that IE10 has done away with Adobe Flash and other plug-ins, as the legacy version of IE10 will continue to support browser plug-ins.
In IE10 Metro, the browser is built with HTML5 in mind. IE10 Metro is directed towards both mobile devices increasing functionality with lower power consumption – a known issue with Flash and a whole new browsing experience in Windows 8. It should also be noticed that Microsoft’s own Silverlight would not be supported in IE10 Metro.
The reasoning behind the lack of support in the browser was said to be for extending battery life for mobile devices and improving security for systems overall.
Metro IE10 is a different way to experience internet browsing and could be the first big step for Microsoft in moving past their stagnant user interface inside old Windows OS to Windows 8.
