I received the Bradt guidebook to Uruguay as a Christmas gift from my sister last year. Having just returned from my long-planned weeklong vacation in Uruguay in November 2012, I can say that the Bradt book is good but not perfect.
The best thing about this book is that it is the only English-language guidebook out there that gives a fully detailed and nuanced treatment of Uruguay's history, people, cuisine, and culture, without which most of Uruguay's peculiar quirks, such as drinking yerba mate nonstop or naming an entire department of the country after the "treintas y tres" would not make sense.
All other guidebooks focus primarily on Montevideo, Punta, and Colonia. This book exhaustively covers those areas plus the rest of the country for people who actually want to go inland and see what rural Uruguay is like. The only other major option is the Footlight book on which is simply an excerpt from the huge Footlight guidebook to South America (and in turn suffers from the terseness typical of guidebooks that attempt to cover too much in one book). All other English travel publishers either do not cover Uruguay at all, or they cover it as a brief add-on to their books on Argentina or Buenos Aires.
The downside to this book, as several have noted, is that it appears to have been written during the early stage of the global financial crisis in 2009 and has not been updated since. But many, many things about Uruguay have changed since then, which are unfortunately, the things that are really, really important to tourists. For example, the book mentions that there are English-language newspapers available at Plaza Independencia. This is incorrect as of 2012; I know because I actually asked at all of the kiosks around the Plaza. (My guess is that the slowdown in Northern Hemisphere tourists during the recession probably caused the local retailers to stop carrying newspapers for those tourists.)
The Bradt book does not explain how to use the bewildering "estacionamento tarifado" system for tariffed parking in Ciudad Vieja and Centro from Monday to Friday which was first implemented in 1996. Indeed, several expats have loudly complained about the system on the Internet because it is so bizarre and confusing (relative to the far more elegant and easy-to-use parking meter solutions found in the United States). Even the locals at the tourist information offices in Montevideo were unable to explain how the system works in English.
There is no explanation of car guards, who are now prevalent in both Montevideo and Punta. I was lucky in that I had encountered car guards before in South Africa a year earlier (and they are thoroughly explained in guidebooks for that country), but visitors unprepared for them may find them strange.
The book does not adequately explain toll plazas, which is strange as they are ubiquitous on the national highway system. It would have been sufficient to explain that all toll plazas charge the same amount for automobiles (currently 55 pesos) to vehicles traveling in both directions.
There is no coverage of Montevideo's rising crime rate; I did my own research on the issue and was able to enjoy a wonderful crime-free visit, with the help of sources like the U.S. State Department's Overseas Security Advisory Council's annual Crime and Safety Report. But again, someone in the market for a travel guidebook like this would expect it to thoroughly address such basic issues like parking, tolls, and crime.
Finally, there was no warning that the observation lounge at the Torre de las Telecomunicaciones is often booked for special events, which means it is essential to call ahead because if an event is going forward, the visitor tour for that day will be canceled. Unfortunately, I discovered that fact the hard way. Visiting the Torre's observation lounge was not a must-do priority on this trip since Montevideo's skyline is so mediocre (relative to say, Chicago or New York), but it was still disappointing.
Overall, the Bradt book is still an excellent resource for anyone planning a trip to Uruguay, but with the above caveats in mind, be prepared to do your own additional research on online sources (like OSAC and Wikitravel).
