To me, the paper version has two advantages.
1. I found it still easier to use it for rules-referencing than pdfs. Yes, searchable pdfs and good bookmarks made it easier, but still. I prefer physical copies of core rulebooks for frequent use and having the supplements and sourcebooks in pdf.
2. To me, it's somewhat moot to have a good-looking, well designed book, if I have it only in pdf. All that futuristic design and excellent full-color artworks are somewhat wasted if the book isn't on the table, being an eyecandy. Moreover, the full-color illustrations of nowadays' rpg books are just plain better-looking in physical, than on a screen.
All in all, if I give up a significant amount of money for a premium rpg book, I'd expect it to perform as a gaming implement and withstand use, while still being pretty. It's too costly for me to be just a collector shelf-decoration (it's a rulebook!). If I want only the rules, I could print the important parts from the book at a local print shop and bind it, for the fraction of the price, but then, it's somewhat sad to having all that excellent design and great illustrations having to be wasted.
'Shrug.' I suppose it's not Catalyst's fault, but I think it'd be good for them to find a more reliable binder, because right now I suspect they're losing would be customers of the physical book, like me, who'd be willing to pay for it. Also it builds a non-flattering reputation, which isn't good if thinking long-term.
WotC had issues with their first batch of the D&D 5e books, but they fixed it. I realize they're a much bigger company and because they're selling a lot of books, the bad copies are disappear faster from the shops, or getting replaced. But still, it'd be good to be able to buy a reliable physical copy of SR5e, because I think it's a gorgeous book.
