Might be time for a laptop...

For organizing music for performance? The locals who perform have switched to tablets. Some do some kind of setlist organization between sets and others do a lot of "swiping" during their between song patter. They also seem to be using them more for lyrics than chords.
I think reducing each song to a PDF that only has one page is a factor for making it work for people who otherwise avoid computers.
The coolest argument for tablets though, is sharing. There is a professional orchestra that comes together for gigs and agility is a key factor in getting the gigs. There are no traditional music stands but everyone has a tablet. Turning pages is at the player's option - some use a foot switch but most use a gesture much like turning a paper page. Bet the devices are networked and the arranger makes changes in real time and pushes them out to all of the players. That has been huge when backing a soloist from out of town who want's to add their own touch or is having a bad day and needs to sing in a lower key.
And I saw some tablet to tablet interchange in a trio where the bassist only played with the others once before and there was a selection they had not planned on doing when they discussed the gig.
That said, for what I do I prefer a big enough music stand to hold two pages side by side, arrangements that fit on two pages, stand lights and lots of clothspins for outdoor gigs. At this point looking cool by not having music in front of me is no longer a goal.
