No, just no. No no no no no, NO. Buy an android device, please. Stop making it sound like bigger screens are a necessity. THEY are not. this is simply a matter of taste. If you want a bigger screen, buy a phone with a bigger screen. This does not mean apple has to do the same, and I hope to god they don't.
Why do you think that Apple can only do one thing at a time? Apple already sells devices with different screen sizes, only the iPhone 5 has a larger screen. If they further increase the screen size, you will have smaller screen options. Why are you upset?
