Hi everybody and thank you for your previous help. I live in Australia and don't know whether to buy a Sony 505 or a Kindle 1

I want one for reading novels only. Nothing else. I'm not sure where to buy novels for a Sony or how much they cost and I hear that there is a 2USD surcharge for every book that I buy for a Kindle 1.
Is it possible to buy a book from the normal Amazon and then put it on my PC and then transfer it to a Kindle 1.
Is it the same for a Sony?

I believe the Sony is cheaper to buy in Aus. than buying a Kindle from the US

Are there any Australians who have tried both and can help please.
Because of my arthritis I can't hold paperbacks any more or juggle a laptop, but I need serious help please

Thank you for any consideration that you can give me
