An understatement of the century. In 21st century, PDF is not suitable for mobile devices. I've read ebooks (ePUB) on my Nexus 7, but it's only usable for serious reading because I can increase the fonts without having horizontal scrolling (in vertical orientation). Without this, I'd probably need an e-paper based reader but even that might unusable for typical A4/letter formatted PDFs.
