You are presuming a certain use case here. I don't think there is a market for this product as a portable, general-purpose computing device. I do think there are a number of other use cases, though:
- Limited functionality, interactive kiosk/infowall type systems - Remote logging and processing systems, particularly for complex sensors - Embedded industrial or robotics systems
