They take up valuable screen space, it is annoying to scroll to the sections you need.
Yeah yeah some PDFs have the side navigation thing. Most don't
With a book I can put in those little flags to bookmark sections, I can easily riffle the pages and scan for the chapter I need, I can hand write in the margins
I often need 2 or 3 books open to different sections, I like keeping them on my desk so I can glance at them when I need to
I've probably cracked $1000 spent on books this year.
My (tablet) PDF reader has bookmarks (which I use to make a TOC if needed) and annotations and cloud sync of the PDFs to my phone for on the go. And it has text search and zoom. Plus it holds hundreds of books that I can carry with me.
Same; avid reader of printed books here. I have more pdfs I can count (most coming from Humble Bundle impulse buying), but nothing beats physical books for me.
I got a remarkable pro, and it's just slightly better than screen. Being able to annotate books is actually a welcomed addition, and the screen is pretty decent. But flipping screen is slow (compared to a printed book), and going back and forth between pages is a hassle. Until we have the speed of a tablet (read: instant), with the screen quality of an e-ink, I don't think I'll voluntarily retire printed books.
Now, I have an O'Reilly subscription (two actually, through school and ACM), but the app is sadly horrendous, as OP mentioned. Hard to believe this is actually their core business.
