- usually costs more to buy
- takes much more time to dissect and scan the book than it takes to crack drm
- PDFs (from scan) have lower visual quality, and are bigger (PDFs have a place... it's difficult to convert something like an organic chem textbook with all the margin diagrams and complex layout into a nice epub, for instance, but even then good PDFs are generated by the publisher, not scanned)
- OCR errors, so text search may not always work even if you can read the original text (you kept is as a pdf, kept it as an image with OCR text as a separate layer only used for searching, or used cleartype-like tech which is similar but basically compresses similar looking glyphs)
- converting to a real ebook (epub) for reading on smaller devices, without extensive proofing (and reformatting if the book uses layout, as in it isn't a traditional fiction/nonfiction work that's all uniform prose), has mediocre-to-horrible results. Line wrapping, layout and OCR errors abound.
I've been wanting to scan all my important mail and documents for a while, but I need the process to be as frictionless as possible for me to actually go through with it and I'm unsure what kind of scanner to buy for that.
Interesting that the DMCA essentially slapped fair use squarely across the face.
I buy text books, not as often as I did because of things like Lynda but I do from time to time. The first thing I do is to cut the book with an automatic saw and give the pages to my amazing Fujitsu automatic scanner.
Then I store the book on a box far away in a storage room.
This way I have a 100% DRM free book I can read whenever I want and weights 0 grams, and I can travel to other countries with it. Most of the time(when buying multiple books) the tree killer version is cheaper than the DRM ebook one, and it does not have your name in all the pages like some bastards do.
Some books never will have a DRM free ebook ever.
