The Sony thing sounds great but for the 2.5 hour battery life. That's right on the hairy edge of being too short. Still, that's very tempting and very close to what I'm looking for. With a screen that big, it could almost be propped on the floor farther in front of us, more like a stage teleprompter.

I've already got the page-turner app sorted out. I don't want PDF, I want it to be source-editable doc format, meaning I had to write a Word macro for crating set lists and paging through them, but that all works now.

Swiping, or even a touch screen for that matter, is not a necessary part of my plan. The page turning will be accomplished with a wireless bluetooth pedal ala this or this.
