I totally agree, the library functions should extend to the SD card, along with the ability for apps to access the SD card. In an android phone, the SD card holds all the pictures, books etc that the apps use, in the Edge they store it on the internal memory. The way the Edge is set up the SD card seems to be only useful for storage instead of being integrated with the device. Hopefully this will be addressed in future updates as the Edge team learns what we need.
