What's a good way to read PDF musical scores on Android tablet in rehearsal and performance?
Agreed, I think MobileSheets or the Fakebook (my favourite) is the way to go. Quick browsing in music and (almost) no delay when swiping between pages. Some of the other features between these two varies, so YMMV. Fakebook is at http://play.google.com/store/apps/details?id=com.skrivarna.fakebook.android
Hope this helps!
