display
13.3-inch e-ink, 1650x2200 resolutionBlack-and-white screen mimics paper and saves battery, but you cannot view photos in color or watch video smoothly; reading text and PDFs is the intended use.
performance
2.0 GHz Qualcomm, 4GB RAMHandles document reading and basic note-taking without lag, but do not expect to run games or demanding apps; the slow processor suits a device built for reading, not multitasking.
storage
64GB internal, no microSD expansionEnough for thousands of PDFs, ebooks, and notes without a card slot, so plan your library carefully once you fill it.
battery
4300mAh, roughly 2 to 3 weeks per chargeE-ink displays drain so little power that you charge this device once or twice a month with typical daily reading; the 490-gram weight stays constant through that stretch.
