Dean Takahashi did a great job weaving you through the inside story on the 360 starting back before the original Xbox even launched. There is a 20 year plan for Microsoft within the industry and the 360 is the next step in that advancement.
He describes some of the internal struggles, each person's background and how and why they ended up at Microsoft (or in some cases leaving Microsoft). I was amazed at how many former Nintendo executives are in the games division at Microsoft. Evidently, having their corporation offices so close in Redmond was convenient for attracting talent, especially after the big Nintendo executive shake-up.
