I came across this video article this am. Couple of great things.
1. Innovation. How do y make a product better.
2. Buy in. Interface with the end users to get to better solutions.
3. Usability. A product that can be used and repaired anywhere just makes sens.

Too Cool. Hope you enjoy this video on off reading wheelchairs.
