I recently had to switch from dial up to wifi which is a good thing,,no waiting for sites to load. No time now to make a sandwich while waiting. Or eat lunch. I thought I might load a book or two to an older Kindle for hubby to read but I am not sure how many gigabytes that would use. I only have 4 which is enough for what I do but I do not want to go over. So far I have only used 1.13 in about 3 weeks. Does anyone know what a normal book would use ?
