First time poster, but I have a pretty good analogy for the iPad mini screen vs retina IMO. For those interested in PDF reading on the mini-- I would compare it to *average* ink jet printers, whereas retina is a laser printer--if you've ever compared prints, you will understand what I'm saying. The text is slightly fuzzier than retina, but by no means is it hard to read for extended periods. Just my 2 cents. Satisfied with the mini. Unrelated question: I see a lot of people mentioning selling iPads. Where do you guys sell used electronics--Craigslist, Ebay?
