Over at the Digital Reader, Nate Hoffelder agrees. See his YouTube below. While Nate used graphics-heavy material, I was grumpy about the display of text-centric content as well. If nothing else, I found the 7.8 inch screen to be too small.
So now—the inevitable question. What hardware and apps are you reading PDFs with, and what are the pros and cons? For a short PDF, I’m not that picky and might even read them with iBooks or a similar app on my 9.7-inch iPad. But for longer ones, I’d go for GoodReader, which lets you not only read but also annotate, edit, and sign. A tap on the key in the screen shot will open up a test note I made. On a PC, I use Foxit Reader.
Of course, PDFs are a fraction of my book-reading: I cherish the ability of ePub to let me display text just so when I’m using it with a good app.
