I've been reading manga through the Shonen Jump app, does that count?

I've got a few Kindle books, but I also have a bunch of books (mostly computer/hacking stuff) through Humble Bundle that I haven't even flipped through.

I have a bad problem of buying books and then having them sit there, kinda like me buying games and having them sit there (but I'm trying to fix that by actually sitting down and finishing the stuff I've bought so far now).
I'm either/or on physical vs digital, but I think I prefer digital at night and being able to read on a train/car easier than a physical book in terms of holding a phone vs book (as weird as that sounds).
I love hardcopy books, but I hate having to store them, particularly as I don't like disposing of books. I can't see myself ever dropping my Kindle or returning to hard copy.
Donate your physical stuff to your local library. Generally they'll do book sales with the donations to fund their programs and stuff. You wouldn't be "disposing" of them, but more giving them away.
