Hi, going to get iPhone 5S and iPad 5. Not sure what GB size. Context : Student, at college. Work with lots of photos. Have 2Gb in textbook pdfs. Have about 15 gb itunes library, but mainly listen to about 4gb of that. Plan on having a fair few movies on the iPad. Take alot of photos on iPhone. Not crazy on apps, but like to have the entire iWork/iLife suit.
