One of the reasons PDFs are still so common is they do their job pretty well, i.e. accurately displaying documents. Any alternative would need some very compelling reason to use it instead. Take Microsoft’s XPS which I think is it’s closest rival. It is an open standard based on XML. It’s built into Windows, Office, and many printers support it natively along with major software vendors, but I can’t think of a single time I’ve come across an XPS file online.
