So Microsoft is finally going to stop supporting Internet Exploder. They're only about ten years too late. I don't use it (other than to test new pages in our web site. If they work in IE 11, they will work anywhere.) and have never used the Microsoft Office 365 suite. We use Open Office here. It is a free and open source office suite that does everything the bloated and expensive Office 365 stuff does.
I am reminded of a story that relates to this.
A helicopter pilot in Seattle got caught in a heavy fog in the downtown area. He was really in a jam, but slowly and carefully maneuvered his chopper until a tall building came into sight. He was only a few feet away at about the 20th floor, and could see people at the windows looking at him. He quickly scrawled a note on a piece of paper and held it up so the people in the building could see it. The note said, "Where am I?" Someone in the building grabbed some paper and wrote an answer. He held it up and it said, "In a helicopter." The pilot knew immediately that he was looking at the Microsoft building. How did he know that? Because it was a perfectly accurate answer that told him absolutely nothing. That's Microsoft all the way.
You were right, I did get a kick out of this.
