I'd suggest that this is a fault, and that you would be best off returning the unit for a replacement. You might run into trouble selling it in its current state.
As to content, you're right that the industry has not got its act together yet. If you're prepared to venture into removing DRM and format-shifting, I suspect that there wil be the content available that you want. You mentioned music theory, and Amazon, for example, has a range of ebooks on that topic.
