" The PC era was about to end."

Not bothering to read the rest. This is entirely 100% wrong. The PC era has not "ended". It's just that we only upgrade every few years instead of every year. And grandma now reads her email on a tablet instead but that was never what PCs were really for.

PCs are still just as much used as ever. We just use other things too, and don't buy a new one every year.

If they can't get this basic fact right then I have no hope for the rest of the article.
