I have a 1st gen 16gb iPad running ios5.0.1. I also have a 32gb 3rd gen iPod touch. Finally, I have a 2nd gen apple tv 40gb. My music collection on the atv and iPod is only 4gb or so, photos are only about 2gb. I don't want to put 4gb of music on my iPad, since I listen to music on my iPod. Occasionally I do want to listen to an album while at university. Do you all think I can use the sd card reader and a sd card and listen to the mp3s on the iPad.
