I am with you jbow. I am getting one this weekend to jam with and even to do the unmentionable and work with creating and writing music with it. From what I can see it also makes it possible to keep your tracks and even rearrange them in the order you would sing them in.
I fail to see the ho hum aspect the others are finding. It may have some limitations but at the same time I think the strong points will make it great to jam with, to write and sing new songs too, and even other things as it keeps developing. The parts, including the filing system seem to be solid enough in the plus version to make it a very usable "toy" indeed.
Let's share notes as we go.
