I too have many hobbies, however the constants in my life are books and music, and I feel I just can't get enough of both. This is where the reader has filled that nitch for me. I don't leave home without my ipod or my reader. I've got a 4gb sd in my reader and it's getting filled up. I feel rich when I have so many books I know it'll take me forever to read them, and same goes for my ipod...only a 60gb, but it's filled to the hilt.
