Online sources are reporting that Microsoft would finally bring PDF editing capabilities to their Word application in Office 2013.
Microsoft Word 2013 would feature the ability to convert PDF files into Word documents for editing capabilities.
This feature would not work perfectly on all PDF files considering the incompatibility of features between the two file formats. But PDFs containing primarily text should work out well.
Microsoft is also going to offer a superior reading experience with both Word and PDF documents in Word 2013 with reflowing text that would fit the display size.
