Lee, I think for me, you have summed it up well. Self contained…I did try something the other night. Had a meeting to go to absolutely unrelated to music… It was a superstorm sandy flood thng. I switche d on the iPad and recorded a few lines of dialog from the group there… Gee whiz it was ideal… Just for giggles it did an awesome job. Now if I can just set it to music 
My thoughts are to be using it for live club type recording mostly a few guitars, bass, cajon, light acoustic. I have hopes there are some very good developments in the works
