What is your "take to Church" Bible that you rely on?
Mine is the Holman KJV Study Bible.
That's a nice one. Electronic or paper?
I use mostly digital now, WordSearch 10 (using Quickverse 10) and Olive Tree Bible on IPad, and on my Iphone, with over 100 downloaded books so far including 18 versions, several lexicons, dictionaries, Greek & Hebrew tools, maps, and lots of stuff from internet favorites like from Biblical Archaeology.com, creation science material from ICR.com, etc. Several warn not to share anything on the internet without written permission, too bad, wonderful charts, data sets, so much that ought to be seen by all students of the Bible. That should be said somewhere before buying, but rarely is.
Whatever is on the screen is bluetoothed on a screen for Sunday School class, and if their phones are capable, they can access my phone library and download some of it (any free downloads, not purchased ones requiring password). That way folks learn how to use their own phones, most only knowing basic voice and texting before we started doing this. I've taught pastors and other ministers to do the same, so much of the "new" is already in use wherever I go. All that keeps everyone "on the same page" literally, and already some are able to find and share their latest finds for all to evaluate in class. We learn how to sift out the bad sites, explore the good ones.
With all that in that machine, I stick with KJV because that's the one I've used all along, memorized, studied. Sometimes I'll parallel another version, or put up several paralleled versions to accommodate folks with their favorites. Several other versions in paper print take too much longer to find a verse when time is short. On digital using the "Search" engine is complicated among most modern versions due to different key words in use not similar to KJV.
All I got for Christmas from friends was more gift certificates to spend on online Bible apps. I got some for Logos Bible, enough to get the Silver which I will put in the new IPad Air that's still in the box. I lost my old Logos Bible 4.3 when changing from my old dying Motorola (no k or m) to Apple, an expensive mistake made worse when going to Samsung Galaxy. I laid my Galaxy on a wet kitchen counter, killing it. The charger port sucks water into the motherboard. No more Samsung or AT&T again. Some of my favorite purchased apps are going cross platform now, so I should be able to shop phones more easily than having to make sure the apps are downloadable.
In the event the battery dies I always keep my trusty KJV Thompson Chain Reference Bible on hand mostly because I can't part with 38 years' worth of added notes and highlighting. The backing is weak and pages getting brittle, so I have to be very careful with it. There's no room left for another side note. Now I save notes in the IPad and IPhone and they sync to the laptop and ICloud.
