When Steve Jobs was alive he would never have gone for this. Apple was a company that paved it's own path no matter what the competition did. Now they just copy samsung? This doesn't seem right. If it is true, Apple will lose some business with me. The samsung phones are too big. The reason I love iPhones is because they are just the right size. Once phones are getting near tablet size, what's the point in a tablet? It just doesn't make sense for Apple to do this because they don't have too. iPhone sales are at high levels right now. Anyway my point is Apple always did there own thing. Copying the competition just doesn't make any sense at this point in the game. They have done so well by innovating not copying.
I hate to break it to you but Samsung didn't invent large smartphones. If anything Apple is catering to demand and not copying the competition. If they were copying the competition then we would have had +4.7" iPhones 2 years ago. Furthermore, there's no definitive rumor that says they'll go away from the 4" model, so your baby phone is still an option until we know any concrete facts. People should be happy that we have more options, It's not all doom & gloom yet.
