"Tests aren't failures as long as you learn from them. ..." But if each iteration of test/ education costs something like 10% of your GNP...you can't afford to fail often. N Korea is bankrupt in every sense of the word...

I do a lot of my reading while I travel and while I have not bought any porn on my Kindle, I like the idea that I can read a Michael Savage, or Michael Moore book without advertising my politics. As a guy, there are books I automatically pass over in a book store because a pink cover markets them to women, and it would not do to have 'Skinny Bitches' fall out of my briefcase in a meeting. With an e-book, that shaming factor goes away. To me, the privacy and compact size make them worthwhile.
