The Kobo Formo is the ideal e-reader to read on for long stretches of time thanks to a number of improvements. The 8-inch screen is larger than most other Kobo e-reader, but even so, the Forma weighs less than most other e-readers. Thanks to the ergonomic grip on the side, you can easily hold the Kobo for long stretches of time. The physical buttons on the grip also let you easily flip the page. Kobo has also thought about strain on your eyes, thanks to Comfortlight Pro, the backlight is automatically adjusted to your surroundings. At night, blue light is filtered so you can fall asleep more easily after reading. Want to read at the beach as well? The Kobo Forma is water resistant, so you breath easy when you bring it to the beach or pool.
