I'm reading there might not be much she can do with it, regarding purchases from the Amazon store.
You mean not much in Polish ? I read not so long ago that the number of these Kindles sold in Poland has been around 70k so not that many indeed... so probably the amount of available content is not that great but there must be something... generally for Poles the idea of paying for any electronic content is a big turn off, It's internet so it should be for free... so with this business model, they won't get many clients here anytime soon.
