Boox Picco Ships With No Onboard Storage, Requires microSD Card

Boox's Picco, a 3.97-inch e-paper reader debuting at IFA 2026 in Berlin for roughly $100 in November, ships with zero internal flash. All book storage depends on a user-supplied microSD card. Even budget e-readers typically include internal storage; the Picco is non-functional without a card inserted — a notable cost-driven trade-off in a nascent sub-4-inch category.
