On the topic of PDFs, a modern PDF is quite different in options / functionality to older pdfs.
I love technology but as it is even with having D&D beyond, Fantasygrounds and every book in hard cover. I will often sit down with my tablet and read scanned pdfs of the books.
Because they are more comfortable for me to read than physical books in certain circumstances and D&D beyond sucks to read at any length beyond referencing imo. (especially if I want to list page numbers for my note taking or refer players to page numbers)
Then you get companies that do PDFs well like MCG and their books (Numenera 2 books especially, really well done PDFs)
I can access it offline, I can bookmark pages or create notes on pages themselves (great for errata or notes on connecting/related rules)
PDFs are a great option and the fact that there aren't any options to buy them has done nothing but lose WotC money, people who want to pirate have been able to pirate since the launch of 5e.
Remember that we went YEARS without beyond as well. Which was especially annoying.
Actually WotC has created a situation where the pirates have a monopoly on 5e PDFs, so I have no sympathy for WotC.
I personally chose to buy the physical products, but I don't judge others given WotCs choices.
Let's compare them to Onyx Path the only other RPG company I buy from.
A few months ago or so I pledged about $90 Canadian for a premium physical Changeling: The Lost core book with special covered and I will get the Changeling: The Lost Core Book PDF (PDF corebook value by itself $25, Kith and Kin: The Book of Kiths $15-$20, Changeling Jumpstart PDF $10, Changeling Companion $10-$15, Seasonal Anthology PDF $5-$10, all 1e's PDFs like around 10 books I think, well over a $100 in value if purchased seperatey), and that includes shipping for the physical book. Also digital changeling dice.
I'm doing the same thing with Geist the Sin Eater in it's current kickstarter.
And these corebooks alone are as big or bigger then the 5e PHB.
Meanwhile I can't even chose to buy the WotC core books PDFs separately.
Man, I would love these as posters for my game room. He sells the Volo's cover as a poster. It would also be cool if he would sell t-shirts with these images without the titles.
