The most useful apps for me on iPhone is process email, read PDF book, Stuck in Weibo, Instagram, Flipboard, other social reading apps and Evernote, a few times play game like sudoku.
I really need one big high resolution screen like Galaxy Note2, Galaxy 4S, but Android is not my favor.
iPad mini is not good to carry, you can not put it into pocket. both iPad mini and iPad are for use at home.
Will iPhone release 5 inch screen version like Galaxy S 4? mobile really become life companion.
