Hoping someone can help me with this. I plan to buy an Android Tablet soon. My main use for it is E-reader. The reason I'm going with a tablet is because I need access to both the Nook and Kindle stores and want expandable storage. I have a question though. My main form of reading is Manga. Manga series can run forever (hell, Naruto alone just hit Volume 60). With a tablet that has an expandable memory, can I put different books on different micro sd cards and then swap them out whenever I want to read certain series?
