Dear Microsoft,

Rather than be afraid of people having Windows installed on a Mac, you should revel in it. At last, people can compare between two operating systems on the same platform. You have the chance to make your OS nimble and quick.

Alas, your history of focusing on monopolizing, and not innovating, makes me think this is unlikely. You have accumulated too much of an empathy deficit for people to care about you anymore.

Sincerely,
Alan
