Amazon was already selling this hardware to Indian customers, and they even had a local retail partner carrying the Kindle ereaders. In fact, that retail partner is the one technically selling the Kindle hardware on Amazon.in, not Amazon. Thanks to Indian government regulations on foreign owned businesses Amazon can only sell directly to consumers if they source 30% of their material from Indian companies. Given that the Kindle is made in China that regulation is something of a problem, and as a result Amazon has to use a local retail partner to act on their behalf.
I have to say that it was a surprise last week when Amazon.in opened for business without Amazon's own hardware. But now we know clearly that was due to a snafu and not a long term plan.
