Here is what Kay got wrong, as far as the iPad is concerned:
- Users can write their own programs for the device
- Battery can be recharged via a network connection
- Data input also based on voice input
- Cassette- / floppy-based data storage
- Power only consumed during state changes of the display and not during viewing of content (although this technology already exists today in form of certain epaper devices)
- Kay viewed the Dynabook as a content creation and viewing device, while the iPad is mainly a content viewing device.
