The iPad to enrich people's live... Sorry, but the iPad/tablets are mostly used for browsing, creating photos and using apps and games. That's not really "enriching" life as i see it, it's a consumer device, not a production device... If you really want to make it enriching, make it non-obtrusive. And i would feel sorry for those whose life really is enriched with a electronic device.
My daughter can create music with Easy Beats 3, she likes the auto drumming thing in garage band because she can record her own songs. She also likes to paint pictures with Paper, she has hot own books so we can keep our drawing separate and so we can print them out or share them. Finally, she makes little animations with Hopscotch. While these are all creativity generators she and I both refer to them as games. I do…
But none the less, although your examples are fine. If you want to really produce things like songs, you're going to use software like Ableton Live. Which aren't adjusted for tablets because of hardware (eg. a high quality audio card) or just don't deliver enough productivity.
I don't have any experience with drawings, but can you name someone who is well known that created their paintings/drawings with a tablet? I presume (except 3D artists, graphic designers), all of them are going for handmade stuff. The rest of them produces them with their computers.
And as you explained it, the drawings and the songs in this case are games, not suitable for production. Production takes days, not minutes. That's mostly the difference between consuming and producing things.
I do hope you or your daughter get more interested though, producing can be great.
