Solid survey of modern design history. I wouldn't have minded a few more images included. Not all designs mentioned in the text had visuals associated with them in the book. Otherwise, it is about what you would expect of a history book. Nicely organized and well written.
Good high level overview, though with 200 years in under 400 image-rich pages, any particular era of style gets at most a short mention. While initially attempting to be somewhat international (though still ending up fairly Anglo-heavy), by the last section (on years 1960-2000) the book is almost entirely about the USA.
I set this as the text book for the Design History class I'm teaching this coming semester. I'm really enjoying it. It's incredible how little things have changed.
