I told this story before. I was migrating an old system to a new one and we discovered that we were still sending faxes to some companies. Our system would create a PDF and send to a server that was connected to a phone line. So we called those companies to ask if we could find another way to send the documents. We learned that they too had a server with a software that would receive the fax and transform it in a PDF.
I was in the US two weeks ago and went up and down with Uber. Five families, two with iPhones and three with Androids. I didn’t notice anything special. In fact, I took a ride cheaper than my Android friend. We were going back to the airport and to a certain terminal. They wanted to go to another. When he decided to change to my terminal, the price lowered to mine.
