Why are you so dismissive? Apple is not the only company that has done this.
Many companies had MP3 players prior to the iPod, but it was Apple's device that completely up-ended the music industry. Now people have access to entire libraries of music on their phone, and a store where they can buy even more.
Can you really say the situation would be better if Apple had blown out in the 1990s and we were at the mercy of Rio and RealPlayer?
I disagree. But it's interesting that you mention Alexander Fleming (it's one m in his name, btw). Fleming actually has some similarities to Apple's role in technology.
Fleming discovered penicillin and its effects, but he abandoned the discovery because he was unable to produce it in quantity, and also did not believe it would last long enough in the human body to cure infections.
It took the work of several others, and fifteen more years, to actually produce an effective drug.
Similarly, those who made various fundamental discoveries and inventions in computing are certainly significant and worthy of attention, but Apple also deserve much credit for making easy-to-use, refined products out of these discoveries, especially over the last ten years.
Giving people better tools makes them more productive in whatever endeavors they pursue. It would be short-sighted to not see Apple's value to society.
Twaddle.
