Earlier quoted context omitted.
It really is completely different. It's like looking at an Etch-A-Sketch, which in the end, is not much different than looking at paper with ink or graphite particles in it. E-Readers are one of those technologies that I'm completely unconflicted and wholly supportive of. E-books should be priced better though, to account for the inability to lend them out to people.
Between the limitations and the lack of a used market, ebooks do seem really expensive compared to dead-tree.
You can also get a decent amount of stuff from various Amazon programs, like Kindle Unlimited. The selection isn't always perfect, but it's not terrible either.
And of course, there are always slightly less legitimate venues for obtaining free ebooks. Your morality may vary, but I'm not sure I see a problem with torrenting an ebook if I already own the paper copy. (Thankfully, some publishers are starting to be reasonable about this, like Manning, and providing a free download if you've got the purchase code from the paper book. Others are not so great - I've tried to buy the ebook versions of some of my Apress books, and the questions that they ask to verify that you own the book, i.e. what page is figure 7-3 on?, cannot be answered correctly using the page numbers from the print edition...). There's also not the same level of organization by book publishers as the MPAA and RIAA.
