Reading books can be a long, tiresome endeavor. One that'll require you to hoist whatever word vessel you choose – be it a tablet, an e-reader, or *gasp* even a book – for hours on end. And if you're a before-bed reader, you're going to need to hold that thing above your head.
This is where an ultra light e-reader, like the new Kindle Oasis, could come in handy. It considers ergonomics (that battery bump is ugly but comfortable), portability (MONTHS' worth of battery life with wireless turned off, of course), and, above all, the option to go light or lighter.
With the cover off, the Oasis weighs about as much as, IDK, a skein of yarn (4.6 oz). As someone who, as a kid, read punishingly heavy books every night, an e-reader this light was unthinkable.
