Tony, I'm late with a response and plenty of good advice has been given already re: scanning. Here's my 2 cents on the MPP, I've been using it for 4 years and it's never failed......... I keep waiting for it to not power up some day, but it hasn't happened YET! With that thought in mind I've recently loaded many of my pdf files to my 32 gig ipad and am slowly transitioning to the iPad in place of the MPP. I use unReal book, but have also downloaded one called Gig Book, that's got lots of potential as well.

I've also purchased an iKlip for the iPad and the holder works great.

I mount the iKlip on a mic stand, it's very low key and can be positioned in a very discreet way as not to block your view of the audience. I will say though the MPP is the old standby and has served me well. If it were to fail, I couldn't bring myself to spending another $900 to replace it when the iPad can take it's place. Good luck with the MPP.
