John Siracusa doesn’t review Mac OS X anymore. But if there’s a true successor to Siracusa’s opinionated attention to detail in an operating-system review, for my money it’s Federico Viticci’s book-length reviews of iOS. Yes, it’s 50,000 words long. But it’s a great 50,000 words. If you like your reviews comprehensive, you will not find one better than Federico’s iOS 10 review.
