Hi Nigel. though I still utilize the Music Pad Pro when I want to view music scores full sized while rehearsing in the studio, when performing onstage, I utilize the smaller much lighter and thinner iPad for those songs that benefit from having a lead sheet to refer to. The ability to keep the iPad sitting at my side and then being able to quickly place it in front of the T4 screen for certain songs, and then quickly remove it without the audience ever noticing is ideal for me. No visually distracting music stand or portable office looking laptop to get in the way between you and the audience. For me, the iPad's the idea sized tablet for discreetly viewing lead sheets onstage.
