display
10.3-inch e-Ink, 301 ppiSharp text and images on a monochrome screen that does not emit light, so it reads like paper in sunlight and drains battery slowly over weeks.
battery
3700 mAh, roughly 2 to 3 weeksOn light reading use (a few hours daily), you'll charge once every two to three weeks because e-Ink draws far less power than an LCD or OLED.
performance
2.4 GHz Snapdragon, 4 GB RAMSmooth navigation and note-taking on light tasks, but not suited to video or demanding apps—Android here serves reading, writing, and document work.
storage
64 GB internal storageRoom for thousands of PDFs, ebooks, and handwritten notes, with no expandable slot; clearing old files occasionally keeps the device responsive.
