Hi, just got my Nexus 10, so far so good. Were traveling next month and I was planning on renting a couple of movies and buying a book or two, its a long flight. I was wondering since Google advertised 20 gig of music storage, I've already uploaded some music, that if all this media is kept in like a cloud and not actually on the Nexus, I may not be able to access this on the plane in airplane mode. My educated guess is its both: yes I can access it and hopefully delete it later since movies eat up space. I would only be renting anyways.
