to be fair,
iPhone could not have existed before it arrived. the technologies were very new. in fact, it was
Apple that enabled companies like corning to make raw material like gorilla glass commercially viable. also multi-touch display. also powerful mobile processors.
they created the entire ecosystem. but you cannot take away the credit from the companies that actually created the whole concept of PDAs and sold them for years. like palm and compaq (ipaq) etc. as they like to say, apple really has not created a brand new product. they just created better versions of existing products. so iphone was not really a magical device.
samsung etc. were already creating similar devices though not as user friendly.
