What a patronizing and condescending piece. All I got from this is that Microsoft has launched something in this space that is really worth taking a look at, if it prompts a competitor to write and publish something like this.
This whole idea, from writing the letter to publishing it as a full page ad in the paper, seems bizarre and misguided.
That's why it is so great. Of course, only time will tell if their display of strength is of fear or confidence.
They could have sent a cake. Or took an ad like the ones Spielberg and Lucas did when the other broke box office records.
