Dean Takahashi wrote an authoritative book on Microsoft's original console, called 'Opening the Xbox'. We're fortunate enough to be able to read a similar work on their next-gen console, a book entitled The Xbox 360 Uncloaked. Takahashi did an interview recently with Kyle Orland, of Videogame Media Watch. There he lays out the challenges of reporting on the industry, and getting publishers to understand the subject matter. Eurogamer reports that part of the book discusses a Microsoft handheld gaming system. From that article: "Takahashi claims the team was split in two following the launch of the Xbox 360, leaving the other half to work solely on reducing production costs for Microsoft's next-gen console. According to the writer, the portable is planned to be released halfway into Xbox 360's lifespan, a strategy to assuage the crippling costs of moving through hardware cycles. A Microsoft gaming handheld has been long-rumoured, the latest occurrence adding fuel to this particular fire being the release of a movie for the company's Origami project. A promotional video for the handheld PC showed Halo 2 running on its screen."
