I also realized after looking over my (physical) bookshelves that I don't actually care about most of the books on there. This is after multiple rounds of clearing out the shelves and making trips to the secondhand bookstore, free library, etc., so it's not a matter of cruft. If I'm honest with myself, most books are "read once and discard," though there is a small collection that it feels distasteful not to keep copies of. Certain classics, or books with particular personal significance, for instance.
The cost of ebooks is an issue, as is the DRM. I haven't experimented with digital lending from libraries so I don't know if that's a solution to the cost problem, but it could be. DRM is... well, a perennial problem for digital media. And it does feel like something is missing in a world without secondhand stores and free libraries.
(Edit: It is in fact a frontlight, not a backlight. Duh.)
I... Really? Y'all ok with just losing a randomly selected pound or two of flesh? I think that'd be pretty exciting, and not in a good way.
Given that most people cannot move their ring finger independently of their middle finger, this seems like a stretch.
I have trouble with some positions due to the ring/pinkie connection, but for me it's more of an internal count anyway, so something like counting a 'down' finger as '1' instead of '0' makes it a lot more comfortable, or even '1' is finger touching a surface, '0' is not - which can involve moving a digit only a few mm or so.
The 1023 thing does require fine motor control of at least ten appendages, though even legs-arms-tongue gets you to 32, if a bit inconveniently.
The idea that having a slightly less comfortable chair would lead to more movement has proven true. It's also relaxing enough to sit in when I'm tired of standing up, but not super comfortable to slouch in, so it encourages better sitting posture.
No disrespect intended to parent posters (i appreciate them sharing their anecdotal experience), but def sobering to see that at the top, and realize "oh, this is the common view of hivemind i'm participating in"
