We simulated a typical university student’s workflow: downloading the eBook on a campus Wi‑Fi, annotating on a Kindle Paperwhite during a 2‑hour lecture, then switching to the Kindle app on a smartphone during a commute. The experience was smooth, with instant syncing of highlights and notes across devices.
