I do appreciate Apples design and engineering but I really hate the slow (death) incremental upgrade process...Apple does have stiff competition and its pretty clear they see that...So I do hope the design has a wow factor...
Everyone is entitled to their preferences. Most smartphone manufacturers try to satisfy a wide range of consumer preferences by making a variety of smartphones: big/small, keypad/slider/touchscreen, fast/faster, etc. Apple makes 2 models the same size. They are the most profitable smartphone maker with the most satisfied customers. I think they know what they're doing. It's the other phone companies that need constructive advice.
The iPhone 4 and the 3GS are still outselling any other smartphone today. The nearest competitor (similar price range, specs & capabilities) has been the Galaxy S line. The original S
shipped (not necessarily sold) 10-12 million units. The S2 ~5 million units. During the same time frame Apple
sold (not just shipped) 65-70 million iPhones.
Google touts Android activation numbers, but never actual sales numbers. Samsung announces these Galaxy S "shipment" headlines when they feel like it. They quit giving specifics in their earnings report. Same with Motorola, HTC & Sony. I wonder why?
The iPhone has competitors, but they are flailing while iP4 is flying. iPhone 5 is going to leave them even further back. The S2 is arguably the hottest 'droid right now. The Droid Bionic debuts this weekend after months of delays, but no one cares. Everyone's waiting for Nexus Prime and Ice Cream Sandwich, but will there really be that many buyers? How well have the past 2 Nexus devices sold?
The fact is the iPhone 4 design still wins the "wow factor" in most peoples' opinion. iPhone 5 will be faster and have better components. Most importantly it will have iOS 5. Apple is not worried about the competition. Apple is worried they can't make iPhones fast enough to meet demand for the remainder of this year.
There's no criticism for people who want a 4.5" screen, 4G, NFC or a physical keypad. There are companies out there who will make devices with some or all of those requirements. Apple will continue to make iPhones that the rest of the people will want.
