I really like e-ink, but the ability to fiddle with page corners & edges in the iOS Books app means it's the only way I actually get ebooks read. Mini's perfect for fiction, 12.9" pro's amazing for PDFs (say, textbooks) or other work that needs large pages (comics, too—it's close enough to the size of a two-page comic spread, in landscape mode, to be entirely readable that way, at least until my eyesight gets even worse)
