I couldn't put it down (figuratively speaking, it was a Kindle
I'm confused. Why can't that be literal with a Kindle? A Kindle is still something you pick up and hold, right? So you'd therefore put it down when you stopped reading, wouldn't you? I mean, yeah, you could then use it to read something different without putting it down in between, but you'd have to put it down sometime. Unless it's, like, some experimental new ocular-implant model.
