My wife still wants a iPad 2 someday soon so she could access online and read ibooks anywhere off our office room with it... just mere ideal and convenient for her for those purposes. She doesn't care about the cameras and retina display since she wouldn't use them, anyway thus she will get a Kindle herself someday for outside and travel e-book reader purpose only.
Everyone has different opinions and purposes after all. iPad 2 improves though it may miss few things many wish for. iPad 3 or later might be the 'one' someday though.
