This would be an excellent starting place for a student of globalization or the application of complexity science to the social sciences. The opening chapters are a terrific synthesis and lit review (as of 2003), clear, well-observed, and with excellent summations of complex works (the Castells trilogy is brilliant, but it's some 1500 pages of eye-bleedingly dense prose: Urry's summaries alone are worth reading the book for).
As it was written in 2003, one needs to apply a discount factor to the globaloney and gee-whizzery: several of the chapters on the future of digital technologies and the decline of the nation-state are just skippable. Also, social scientists should simply be forbidden from coining neologisms and acronyms, but that vice is far from unique to Urry.
Urry's argument is that sociology has for too long taken an atomistic approach to "societies," which, if it was ever justifiable, certainly isn't anymore. He employs complexity science without over-analogizing between physical and cultural systems, an easy trap to fall into.
In all, while a bit dated, Urry's brevity and clarity makes this a solid and useful read.
