Extensibility
The future of the Talking Book Device should actually be a platform:
- It should be based on one hardware platform, that could be versioned but will always be backward compatible*.
- It should be extensible, allowing a low price for the basic unit, but the opportunity to purchase add-ons later, such as:
- additional memory
- LCD display
- rechargeable batteries and recharger
- personal/group solar panel
- mobile phone cxns for modem capability?
