I bought a Kindle Fire to ensure that MobileSheets would work on it, and I have to say, it's nearly impossible to use with sheet music unless you view it in landscape mode, or have eyes like an eagle. In landscape, it's usable, but you have to rely on the automatic scrolling, as the Kindle Fire has no bluetooth support, so it's definitely not ideal. I could definitely see using the Kindle Fire to view lyrics, guitar tablature, chord sheets, etc, though.
