I am a boring old fart. No friggin' tablet for me. I was invited to a jam session which I attended a few times until I got tired of being the bass player playing with six guitar players who all strummed pretty much the same thing.
And they all had tablets! Somebody would call a song, then each one would take five minutes trying to find it on their tablet, then there would be a problem because they were in different keys. It would take 10 minutes to get a three minute song organized.
I quit.
The people I play with now use paper charts, and we each have a book of jazz tunes four-inches thick or several or we play blues or three chord wonders that everyone can pick up in a hurry.
Don't blame the technology when they use the wrong tools and the wrong software, and don't learn how to use it. That example makes me think you can play bass lines on an regular electric guitar because it has the same low strings. I can find any tune out of 4,000 in a second using MobileSheets Pro, but I use the Set Lists feature for my Church gig and just keep advancing. Over the course of a year it's a huge number of songs, different ones each week. I can notate, annotate, and write on my tablet to my heart's content because of Samsung's stylus is just like I was writing with a pen or pencil on paper. I even put my practice, lessons, and woodshedding on the tablet too.
It only took one session with my tablet to realize there is no going back to paper. Getting ready each week now that I'm setup takes a minute, no filing, putting in a binder, and returning it to the big music file box. AND no miss filings either. No fixing the holes with tape because they get torn over time. My office has been paperless for years, long before Covid. I feel like an idiot I didn't do the same with my music sooner.
I use my paper size tablet to write on like pen and paper so taking notes is just as easy as writing on paper and I've been doing that 7 years already.
You absolutely need the right robust and flexible gig ready software, not just Adobe reader, that is more important than the Eco System.
I do get preferring paper and no one should switch unless they want to. And wasting time between songs is a real pain, it kills the mood. But there isn't anything that's done on paper I can't do on my tablet, and it's backed up unlike paper. I'm not saying you should switch, just that it can be done and done well and I think actually faster, not just lighter. I'm not ditching or selling any of my paper fakebooks or lesson books.
I've down sized my amp, my gear, use neodymium speakers, and downsized my gig bag too. Why not ditch all the weight of the books too. We're not getting any younger. and lighter can be better. And Tech is not just for the young.
I really do regret not doing this sooner.
