Windows 8, the next OS coming from Microsoft features the slightly improved browser called Internet Explorer 10.
The metro user interface supports "next generation" (that is fat, imprecise fingers that are useless for typing) user interface methods, and older 'classic' mouse and keyboard input is deprecated. Inside the same metro user interface, a different browser, Internet Explorer 10 metro edition has a new 'feature':
"Controlling the site experience"IE10 on Metro will have a Microsoft-vetted whitelist of what sites are and aren't allowed to have special privileges. As of now, it includes plugin support like Flash, as well as camera, microphone, printing,
peer to peer, and gesture support.
Those sites will not be allowed to be displayed in Windows 8. Developers of those site must make a 'app' for Windows Store which contains it's own guidelines like no peer to peer (ie bitcoin). Flash content will also be not allowed - goodbye flash games. Unless they are included in Microsoft's CV whitelist.
