So just to recap, at the moment we have bookmarks which are free, paper thin (because they're made of whatever piece of paper, ticket stub, etc. I have around) barely stick out from book but can stay with it, and feather light. When I start reading and stop reading I simply move it to another page. I can and do own dozens with at least one stuck in many books. I can have multiple in one book. They physically bring me to my last-read page.<p>Instead this is something expensive, thick, with a battery that could ignite and a knob I must turn, protrudes a lot and/or I must carry separately, slow to resume and slow to save.<p>This doesn't read like an April Fool's joke. This reads like an Onion or SNL skit mocking the tech industry. What am I missing?
