Now, the original iPhone admittedly didn't come with every feature right out of the box — GPS and copy and paste come to mind — but there's no question that the iPhone revolutionized the smartphone industry and injected a much needed breath of fresh air into a market that was largely stagnant.
As is typically the case, the original iPhone launch brought along with it a number of tech pundits who were quick to lambast Apple's foray into the smartphone market. For a variety of reasons, pundits were adamant that the iPhone, at worst, was bound to fail or become a niche product at best. But almost comically, many of the features that the original iPhone was overwhelmingly criticized for have now, to a large degree, become standardized on many of today's more popular smartphones. Further, one can make an overwhelmingly strong case arguing that the design principles that went into the iPhone, going all the way back to the original, have helped form the blueprint for what has since become the modern day smartphone.
