Good morning folks, my wife who is sighted has decided she would like a kindle book reader, I know that not all books are able to be read by a TTS but was wondering what model to buy that would suit both of us? I understand there are models which are 3G? wireless? Would probably just download from the kindle store to our pc and transfer to the reader, assuming this is possible?? Any suggestion for which model to go for would be great! Thank you! alistair
