The iPad Mini 3 ranks among the very best tablets for reading ebooks. PDFs suck on any tablet or device or even when printed. PDFs are the absolute worst common ebook format because they were designed to transfer secure documents, not for reading as such. Nevertheless, the iPad Mini 3 will do a good job of displaying PDFs, and it will really excel when it comes to true ebooks like Kindle and ePub formats, and magazines look fantastic too.
