Dogfight: How Apple and Google Went to War and Started a Revolution is a look at Google’s introduction of the Android cellphone as reaction to Apple’s iPod and visa-versa. How the smartphone market was created and expanded by the back and forth between these two companies that were one quite friendly. Vogelstein does a good job interviewing people inside both Apple and Google- usually the principle actors. The book does suffer when Vogelstein presents his own analysis- some of the pros and cons of each platform are quite subjective. The book is padded out, but not unduly so with information on the convergence of media before and after the smartphone. Vogelstein uses his reporting on the court cases and the patents and patent law to explain the legal battles between Apple and Google. Patent Law is a book in and of itself.
