Android is a fine OS, but no one can deny that the original iPhone was truly an innovative device and I mean that in the traditional sense of "innovative".
Today, companies through the word "innovative" around constantly to describe incremental improvements. In truth, innovative should me a major change, something that creates an entire new class or fundamentally changes the way we accomplish things. The original iPhone started that, it was innovative.
The traditional sense of innovation is any incremental or revolutionary improvement. Anything that is new to the world is innovation. The fingerprint scanner on the 5S is innovative because it is the first to use that specific method of scanning technology in a phone, even though Atrix had one first, it didn't use the same technology. Retina display is innovation. Improving the camera megapixels is innovation.
