PC-DOS, the brand-new OS created by Microsoft for IBM, cost $40. So which of the three became the default choice of consumers? And since ad dollars seek out the hottest newspaper the same way developers bet on PC-DOS and ignored CP/M and UCSD, Winer argues the best price for a newspaper on the iPad is $0. 'If you can get Steve to bundle your newspaper so that every iPad user gets a free subscription,' advises Dave, 'when you look at yourself in the mirror you'll be looking at one smart and newly rich person!'"
