E-books and notebooks with cloud services support

Cloud services

— online storage and synchronization that automatically transfers purchased books, personal files, and edits to your device, and also saves reading progress, bookmarks, and handwritten notes; on e-readers, this provides "read at home — continue on the smartphone," while on electronic notebooks, it adds backup, handwriting recognition to text, and quick export of notes to PDF. Compared to offline USB connection, cloud services are faster and more convenient for everyday work, allowing you to restore your library after a reset and share documents with colleagues, but they require an account and internet, so for private materials, it may sometimes be appropriate to combine the cloud with local transfer. Typical scenarios include syncing a large library between an e-reader and a phone app, sending lectures from a notebook to email/drive, and searching through all notes from any device.
