Does anyone have a working Kindle eBook reader they no longer use gathering dust in a drawer? I've an elderly friend (95) who's an avid reader, but not in the least technical and doesn't want to be. However I have a lot of eBooks she might like to read. I've no hope of talking her into a mobile phone or tablet (nor would I want to) but I think a Kindle reader might be just un-techie enough to get under the bar and gain her acceptance. I thought I had an old Kindle myself, but can't find it anywhere so I must have thrown it out when I moved.
Any help appreciated!
