I too bought that book ... and honestly after living here for nearly three years i can tell you too ignore it ... its very negative. Zurich is great, Swiss folk are nice, you just have to accept they have some funny Rules.
BTW ... California to Zurich, i would do it the other way around
My family live in a house about 15mins from zurich main station next to a very pretty wood and lovely swiss village, we are looking to move back to London in April /May ... if you want i can show you the details.
Best of Luck with it all
