Apple started selling in the USA the iPad. As a marketing campaign it is a text book success that is likely to be studied for some time.
For me it is a truly hyped product, with a computer press that is bought and sold on the idea that the iPad will be the saviour of the press industry. The iPad being the vehicle that sells its content.
Apple sells closed systems. It has shown with its iPhone the extend of its control to ensure that only those products that meet Apple's strategy will be available. As the objective is profit, open and free information is not in Apple's interest; there is no margin.
The iPhone has had several iterations without providing language support for languages like Hindi, Malayalam... Given that the iPad is associated with paid for content, this may change. It is not the need of people but the need of industry that will be served.
There are two reasons why I will not buy an iPad; the most relevant is that I prefer to read my books in bath.
