Here are all screenshots of the built-in Windows 8 PDF reader. The integrated PDF reader is pretty decent and is using the very elegant Metro UI interface.
While we’re talking about the fancy Metro UI, make sure to check out this awesome Rainmeter theme for Windows 7, a Windows Phone 7 Metro theme for Windows 7 .
I’m already looking forward to this integrated PDF reader. Adobe’s PDF reader is still rather slow, I hope that the integrated solution is a bit faster than the stand-alone PDF reader. I’m also wondering how much Microsoft paid Adobe for integrating the PDF reader.
