It is. It’s really good.
I agree completely. Even without a retina display, the mini is a thoroughly pleasant device for reading. And dictating script notes via Siri feels enough like living in the future that I barely miss my flying car.
John’s feelings about the inexpensive but unpretty GoodReader app match mine, and my recommendation hasn’t changed since I wrote about reading screenplays on the iPad Maxi: Spend a few extra bucks and get PDF Expert. It syncs with Dropbox, exports annotations as text files, and won’t hurt your eyes. My only complaint is an old one: with no ability to offset page numbering (to account for page 1 of the PDF corresponding to the unnumbered title page of a screenplay), your exported annotations will be off by one page.
Small price to pay for a hundred screenplays in your pocket.
