I usually preach from my Logos app on my Kindle. Recently during a sermon, my logos app froze and I had to wing it from there without my sermon or notes. I guess I could have restarted the app, and just winged it until my app was back up, but I was most of the way through my sermon, so I didn't bother.
I have a Samsung tablet as well and I thought about bringing it in the pulpit with me as well as a backup.
Do any of you regularly preach from Logos or even from a tablet using Word or something else?
Do you have a backup plan if your tablet or app takes a nose dive?
