The first and best of Doctorow's books, Down and Out touches is one of those books that are "relevant" today, but likely won't be in 20 years or so once many of the issues that Cory cares about are either resolved or we're living in a post-apocalyptic world and therefore they don't matter anyway.

While the concept of Whuffie is a bit too utopian for me (and a logistical nightmare when you think about the massive computational power that would be required to crunch the complex algorithms to calculate Whuffie scores in real time), this book is a pretty fun read. Don't expect a whole lot of depth from it, though.
