Yeah I think you're right - I haven't read the book, but I understand the thesis and this seems like a good example of it.

Some companies can still see the writing on the wall and adapt though. When the iPhone launched Google immediately scrapped their blackberry like phone design and went all in on their v2 screen based UI. At the same time Ballmer laughed at Apple and the Palm CEO was saying even dumber stuff.

I suppose it's frustrating to see it in the comments here too. I think people are just generally bad at seeing this kind of thing even when it's right in front of them, even when in theory they're the best type of person to notice.
