I, too, tend to notice typos in the books I read. Sometimes they can be very distracting. The really glaring errors seem almost an insult to the reader. But I love books -- the paper, the typeface, the heft of the fat volumes or the cuteness of the small ones, the illustrations, the footnotes -- not just for the plots or the data imparted, and I can't imagine a world without them, as some futurists predict.
