Are you seriously going to say that Samsung isn't doing amazing business right now? Apple and Samsung both dominate the smartphone profit pie. Also, that 50 million number is just a rumor for now. Not saying it won't be true but I'd hold off claiming it as a fact. Also the S4 was released in April and the latest iPhone's in September. Plus you are comparing one model versus the sales of the 5S/5C and 4S combined. Please don't compare apples to oranges.
I also never said or implied Apple wasn't being innovative. What I said originally was that they got conservative with the iPhone in recent years. This has not meant bad business per se but I and many others bought an S4 because we felt Samsung was taking more risks and bringing something more to the mobile market at that time compared to recent iPhone's. I personally felt like I was taking a risk as the S4 was my first Android phone but honestly I was much happier with it compared to my iPhone 5 which I used since it launched.
If you are going to tell me that the only reason Samsung made larger phones was being they needed a way to keep their device powered on then I don't even want to waste my time talking to you. It blows my mind that Samsung engineers are mindless to some of you but Apple, no no, Apple engineers are the upper crust of sophistication and intelligence. Samsung made the SIII and S4 the screen sizes they are because they determined that's what they wanted their flagship to be. Nothing more. If you don't agree I don't know what to tell you. But it amazes me how dismissive of Samsung you are.
