I shop at Barnes and Noble a lot, and I even subscribe to their membership program (for an annual fee I get 10% off purchases in-store and free shipping online). i dislike the way physical books take up so much space in my apartment but at the same time I can't in good faith buy e-books when they're covered in draconian DRM. I also can't get over the incident from the early 10s when Amazon deleted 1984 off of their customers' kindles.
My apartment is running out of space for all these books, and maybe the solution to this is that I need to borrow from the library more often instead of buying my own books. I really wish I could have an e-reader, but again, I don't want to spend money on things that will lock me into a single vendor indefinitely and might just arbitrarily go away.
I learned my lesson in the early-00s when online music purchases were DRM'd and I lost a lot of my collection due to Yahoo music shutting down. I also remember one of the problems being that purchases made in one store would not be compatible with a competitor's MP3 player, which locked you into a single vendor. Couldn't switch to iPod because it didn't work with the DRM that was designed for my Dell DJ (which was a POS that broke all the time but I had to stick with it because of my existing music collection).
I'd hate to have that same problem but with books instead of music.
