iPad newspaper-WallStreetJournal(WSJ)

talking about the iPad tablet, One application which is estimated will be the mainstay in the iPad is a newspaper subscription. Wall Street Journal (WSJ) responded with a specific application. As quoted from Engadget, Saturday (3/4/2010), this application will have a subscription fee of U.S. $ 17.29 per month. Costs that allows users to access application specific content that can not be accessed on the WSJ online version. In addition there are special abilities such as personalization, 7 days archives access and storage to the rear posts to be read offline. If you are not subscribed, applications are also available for free WSJ. But access is only restricted to the major news and market data. Now, back to the price problem, apparently the WSJ is not ‘willing’ to lose customers print newspaper. This assumption is reasonable because the price ejected WSJ subscription print version, according to Engadget, is U.S. $ 11.67 per month or about USD 100 thousand. As can be compared to the above, the price of a digital version of the WSJ is more expensive than the print version. Does this kind of business model that will be followed by other newspapers?
