Paul Thurrott and Rafael Rivera have today revealed a couple of Windows 8 features which includes the PDF Reader and Internet Explorer Immersive UI. Both the features extensively use Metro like interface which seems to be the alternate of Aero interface in Windows 8.
With the addition of the default PDF reader, it seems that the days of Adobe Reader are finish. He added that the application itself is simple enough and it displays PDFs in full fidelity.The ability to zoom in and out, and a page scrubber on the side of the application window for document navigation has been added. The PDF reader also supports the side by side page views. This is the first app which utilizes the new AppX application package type .
They have also revealed the immersive version of Internet Explorer which very much looks like the Windows Phone 7 Internet Explorer.” There isn’t much to see yet, though the browser does work. Browser history is implemented similarly to tabs in IE Mobile, with square, simple thumbnails. But IE Immersive picks up some nice site colorization functionality from desktop IE 9 while displaying those tabs in the tabs screen.”
