A rather unsatisfying confection in the end for me (an internet marketer rather than creative/designer).
Might be brilliant for inspiring creatives but I doubt it and I'm just not sure a book is a great medium for showcasing websites these days..
The authors profile 50 websites from various categories. I could not discern what criteria were used for choosing the 50 but some are big and predictable (though one senses that mainstream sites like Amazon and eBay are only grudgingly included in the list) whilst the majority are slightly interesting and innovative but generally pretty marginal in impact (and certainly in relevance to online marketers if that's your area).
Definitely some minor interest and some nice screen shots (if that gets you going) but with the vast array of goodies on the web this was seriously disappointing, pretty much out of date as soon as published and definitely not worth a fraction of the £[...] I paid for it.
Definitely avoid if your interest is website design for the majority. Probably avoid if your interest is leading edge web design too (as it's poor value).
