My beef is not so much with his factual accuracy, as that he buys in hook, line, and sinker with (and actively promotes) Apple's marketing narrative. The things he mentions are those things Apple mentions in their marketing spiel. Hell, he even refers to "retina and non-retina images" on the web, as if the Internet is a mere extension of an Apple product and, like third-party apps, has simply yet to catch up to Apple's vision.

The ad hominems against Gruber (and they are ad hominems) stem from the fact that he shows no ability to think, or write, anything that Apple doesn't deem he should think and write (in regards to Apple). He is, for all intents and purposes, a member of their marketing department, yet he is at least nominally an independent blogger and reviewer.

There's nothing wrong with liking Apple. They make great products. But to so uncritically buy into the hype and narrative, then claim independence of thought and word, rubs many people the wrong way.
