His attention to detail is great, though, no doubt about that.
Not a Hypercritical or ATP listener, huh?
Also, there's other very good straight to the point reviews. John Siracusa's review is not supposed to be a TLDR laundry list of changes, there's no point in being trapped in the reviewed product and forget the things that led to it.
A few of the things he talks about regarding the UI changes are already on Windows, but he talks as if they're a new invention. While he might be talking to a 100% Apple audience, I think it makes him look silly that he doesn't mention they're not Apple-original features.
Eg. windows that are semi translucent with the background blurred came with either Vista or 7. That annoying animated focus circle is in Office 2013.
