The introduction of the first iPhone brought a slew of new features to the mobile computing landscape, and Apple hasn't stopped the advancements in the 14 years since the original product's release. "A widescreen iPod with touch controls, a revolutionary mobile phone and a breakthrough internet communications device," the late Steve Jobs told an enthusiastic audience at MacWorld in 2007. When the audience realized that those products weren't separate at all, but a single device, a cascade of applause erupted in the San Francisco auditorium. While the original iPhone let users access mobile technology with just the touch of a finger, modern iPhones provide computing power that could only be imagined back in 2007.
When the iPhone was revealed to the world, the best smartphone options available were clunky and difficult to use. Arguably the most polished phone at the time was the Motorola Razr, which has since been revived by the company in an industry-wide quest to capitalize on nostalgia. Even the Razr was flawed, as it had a low-quality camera, next to zero storage, and no input methods aside from tactile buttons. However, before the iPhone changed the market for smartphones, there was another Apple phone, and it was made in tandem with Motorola. Apple called it the iTunes Phone, and it was unveiled at MacWorld 2005. It was about as awkward as might be expected and was essentially a Motorola phone with a built-in iTunes application that could store about 100 songs.
