Thats my point. Both get you to the destination. Nothing changed much since 1956. Engines became efficient and more powerful as did the drivetrain,handling and car designs but fundamentally the car does only 1 thing and thats to get you where you wanna go. That may change with Elon Musk's ambitious self driving cars but for now we are stuck with the same cars except they are faster .Cellphones till 2007 had basic web connectivity, some small apps and games but fundamentally the only things they were great at was just to communicate with other people. Without a SIM, you have a paperweight in your hands. Thanks to Jobs, there are so many things the iPhone is good at. I browse more on my iPhone and iPad more than my PC. I type documents,sync all my fitness data and even use it for some professional work and the best part is it all works as if its deisgned for it
Finally you understand that the difference between an iPhone and a cellphone is far greater than a 1956 vs 2016 automobile.
