Re: books vs screens
"And no CCS payment for sequestering carbon. "
Really? Your reader works by magic?
Paper is absolute carbon neutral product, every gram of carbon it has, is taken from air. Almost all of the carbon needed to make it, is also taken from the air.
And the finest part of it: if you *don't* use the tree to make paper out of it, all the C it collected, is circulated when the tree rots. So paper is literally removing C from circulation.
Totally unlike plastic and electronics used in e-readers. Using CO2 as an argument for e-reader isn't really flying at all.
But other things.
Having 600 books in one device means you lose all of them when the device eventually and inevitably breaks down. Or you lose your reader. Same problem, in lesser extent, applies to phones: When your digital personality is tied to phone, losing the phone means you cease to exist. Or, even worse, someone else is now you.
That's a real problem when you try to recover from it.
Also carrying whole library with you seems really odd, digital or otherwise: Reading a book takes a good while so not many needed for a trip.
Then there's the cost and digital restrictions imposed to said books.
E-books tend to cost the same as paperbacks, +-10%. That's way too much for bunch of bits and aftermarket is basically zero because of DRM: You can't resell any of your books. Or buy used books at $2 from thrift store. Even less getting them free from a book exchange.
One Kindle costs about 50 to 100 (used) books, it's even more expensive than large bookshelf.
Format of a e-reader is one page (of a paperback) or some part of that, that's not much. Hard cover version have larger font and larger page. At cost, of course, but you usually can buy one. No book covers, no cover art, just plain text. Not really significant, but still cons.
Screens (all of them) have nasty glare and are specifially picky about lightning and resolution is far less than what print produces. Kindle isn't light either, it weighs about the same as a hard cover book printed on good paper, so you need a surface to put it for reading.
Then there's' the browsing ...Not too bad page by page but try to have a peek at index in the middle of reading and it gets complicated. Having a one page display has it's limitations.
