I guess I’m a bit like this with a lot of things of this nature. For example I do almost all my reading on ebooks now but there’s no way I would trust Amazon, Kobo or whoever to hold all my ebooks so I can re-download them anytime in the future. I download all my ebooks into my own database and then side load them onto my reader. I had one supplier go bust a few years back and if I hadn’t kept my own copies of all the books I’d bought from them I’d have lost them all. So I never trust my data to any organisation period (including keeping data backups on the ‘cloud’. I manage my own backups always.)
So I guess that makes me a bit of an anorak too! Hey ho!
