I've not used a kindle but I can see how good they are if people are short of space. Husband has one which he uses on holiday, I take a couple of books with me and often buy one when away in UK. There's always the odd afternoon or time when I'm not doing much so I read, it's relaxing. Like you LR I donate old books to charity shops, ones I'm not likely to re-read (some came from charity shops). I suppose we may have to cull when we retire and downsize.
