Yes, for me this has probably been the biggest and also the easiest one. So much data, in my case, willingly given to one of the worst companies from a privacy stand point. Every photo, email, etc, etc. Email was a very easy transition over a few months, I’m shocked but how quickly I’ve got the point of only logging into gmail once every 6 months or so just to check if anything still going there. I realized I didn’t really need all of my photos going to their servers, now running no backup for photos although my plan is to start using iTunes for periodic encrypted local backups to my PC, mainly for photos and contacts.
Definitely prefer a real book, of course a ton of convenience to be gained by the various ebook readers. One thing I’ll say I have a very hard preference for though is at least an e-ink screen when reading on a digital device. Spend enough time on backlit screens, way nicer when I can’t have a physical book to have e-ink and regular lighting.
