Now that Donny has found what fits his needs, and this has NOTHING to do with what gear ANYONE else uses, but I just want to say that last week I worked two gigs with my guitar player friend in NJ ...
He has been using the RCA Pro12 tablet along with Mobile Sheets Pro for playing backing tracks and scrolling lyrics ... I was quite impressed with how well it works (I don't use mine the same way), and answering some requests 'on the fly' resulted in no down time ...
It's great that there are SO many options available to fill our personal needs and budgets ...
