In countries like US, UK, Australia etc, eReaders (like Kindle, Nook etc) are very popular - they're convenient to carry, hold many books and eBooks are cheaper compare to paper books.
In India (and other alike countries), however paper books are priced very cheaply, comparatively. It's like book of 30 USD is available in 500 INR (~10 USD).
How Amazon and others are going to sell their devices in countries like India? Will people spend 15 USD more (considering eBook version is priced at 25 USD) for convenience, every time, for each book?
As there is no separate cheaper 'Indian' edition available for eBook... If they'll make it available, people from US, UK can buy it too…
