Another example, I'm not sure it qualifies, is that Gruber never liked the brushed metal theme and the inconsistency with which Apple applied it to different applications.

Apple did eventually retire the brushed metal theme and is getting a bit more consistent in the styling of their applications. Still some way to go here, too.

Apple and Gruber has generally diverged in how they think the Apple Human Interface Guidelines (HIG) should be applied. Gruber has called them out for not applying it as consistently as they did in the past.

But regarding the HIG, it seems Gruber has resigned and is now calling the HIG basically defunct.

I think in general, Gruber is not trying to be right/wrong vs Apple, not trying to offer a strong opinion, except in some unusual cases (see: AppStore rejections). Mostly, he is just trying to understand Apple, and to offer his analysis since Apple is famously quiet and other analysts are often clueless as Apple is a bit of an oddball in the corporate world.

Well, the first and most obvious example is the inconsistency and arbitrariness with which Apple approved or rejected AppStore applications. Gruber was probably Apple's most vocal critic at the time. Apple have improved a lot since, but still have some way to go in that department.

>Another way of asking this question is, can you name three times that Apple and Gruber differed, but Gruber was in the right?

I can.

1. The App Store approval nonsense. 2. The missing white iPhone. 3. Software patents. 4. He's also picked on design choices of Apple with iBooks and believes the Kindle app is better.

These have all occurred within the past year alone. It's fine there are those that disagree with Gruber but I find it best to attack on the merit of what is written and not his bias. It is the easy way out.
