I have had my MPP for about 9 months. I have about 750 songs in it so far. The project (to migrate lots more music to it) has been on hold as I bought a new S900 and have been working on styles/registrations etc. to get it ready to gig, and other misc. "life priorities". I do like the MPP, I bring it to most gigs now. I can still move faster in a single book (find songs, in a book I made that I know real well) - but for more than one book the MPP wins hands down. but the MPP beats bringing 3, 4, 5 books to a gig!

It is a good amount of time to do all the work needed to migrate music to the MPP, but I feel it will be worth it .
