One of the nice things about Windows 8 is native PDF support using the Reader app (though it badly needs a hand tool). It's pretty basic but it would be a good fit on Window Phone 8. I'd much prefer to use it than the slow, clunky, updated once every 2 years Adobe Reader app.
So, is there a native or Microsoft-published PDF reader for WP8? Or can Office Mobile open/convert PDFs like Office 2013?
