I would suggest creating a software suite for Boox devices for mainly: converting multiple formats, to best fit the released devices, and its characteristics [screen size, resolution, etc], with a demo screen of the output file, as this would save time-related to multiple unsuccessful [undesired] export attempts.
Other features can include:
- New software [OS] updates notification & push
- Book store
- News [newspaper] subscriptions/channels, RSS, with offline content synchronization
- Appstore
- Library Management & Backup
…much more - maybe I am dreaming
