Got a gig in mine, got music, movies, music videos, ebooks. I'm using a amp/dac for entertainment on flights. I also move stuff from system to sd card, keeping it clean, and back up my sd card. Sd card is also good for upgrading older phones to new os's, open source android built os's, and making snapshots to revert if need be. I hated it when google tried to force people to use cloud, because I didn't have internet on flights, on the highway for streaming music, or when I went to my cabin. The control of the big corps is annoying.
