Second time around: Aidan Koch takes another stab at a think-outside-the-tab eReader. This one attaches to your keychain and, like the tamagotchi did before it, keeps your wallet and phone company. Nothing wrong with standing in front of your house for a few minutes until you finish the chapter, blocking old ladies and delivery men—it’s a free country. Develop an impressive thumb callus from the constant scrolling—like the summer you mastered the monkey bars. When people try to read over your shoulder on the bus, you can easily put your whole hand over it and give them a dirty look. Choose wisely with this one: best to stick with novellas, poetry, and experimental short stories. Not recommended for hidden keys.
