    Verdict

    The Kobo Sage is a premium 8-inch eReader featuring a high-definition E Ink Carta 1200 touchscreen with a 300 PPI resolution (1440 x 1920) and a 1.8 GHz quad-core processor. Main characteristics include 32GB of internal storage, IPX8-rated waterproofing, and versatile connectivity via dual-band Wi-Fi, Bluetooth for Kobo Audiobooks, and USB-C. Its primary pros are its ergonomic design with physical page-turn buttons, integrated Dropbox and OverDrive support, and compatibility with the Kobo Stylus for note-taking and PDF annotation. However, notable cons include a relatively short battery life from its 1,200 mAh capacity and the fact that the Kobo Stylus must be purchased separately.
