Ummm.. I have been reading Ed's articles for a LONG time, he bashes EVERYONE... Microsoft included!
He isn't a fanboy of anyone(Maybe Linux if anything), I think he is giving Apple sound advise.
Then you haven't read your history either. Apple's past try at licensing the OS was a HUGE failure. They only started on the road to their current financial success and their huge marketshare increases after they stopped the licensing.
