the biggest e-reader, like the Kindle Oasis or Kobo Libra, has a clear edge for book lovers. The e-ink screen is way easier on the eyes during long reading sessions—no eye strain or glare, even in sunlight. Tablets, like iPads or Galaxy Tabs, are versatile but the LCD screens can be harsh, especially at night. E-readers also last weeks on a single charge, while tablets need daily charging. The biggest downside is e-readers lack color and multimedia, but if you just want to read books, they’re the best choice by far.
