I use a product called "MusicReaderPDF"
http://www.musicreader.net/

Works best when each song is in its own PDF. The library function is very good. You can easily create set lists which can be saved and even shared with others. The PDF rendering engine is not as fast as Adobe, but if you have a reasonable CPU it's not a problem.

The screen layout is setup to enable page turns by touching the screen - the right hand 2/3 turns forward, the leftmost 1/3 turns back. I also use a double foot pedal programmed to <Page-Up> on the left pedal and <Page-Down> on the right pedal - left pedal = back, right pedal = forward.

I was originally using it on an Atom powered 11.7" slate which simply wasn't good enough for me - too small a screen and a bit slow doing page turns. Upgraded to an i5 powered Acer Iconia 6120 (dual screens, Win7 x64, doesn't like being turned portrait but will do it), pur MR into a window and stretch it over both screens and voila, the best electronic music stand available.

Only real downside of the Acer is battery life - driving 2*14" screens only gives 2 to 2.5 hours but I'm working on a solution for that: just need a 12V DC to 19V DC converter that will handle about 3.5A. Will probably have to make it - that way I simplify things a lot by not needing a full 240V inverter.

In the meantime, there's almost always power around, you know, for those new fangled electrywockel thingies, umm, I think they're called "electrickery guitars" or somethin'.

You're only paranoid if you're wrong!
