I actually already have a BK-7m... so what this can do is quite relevant to me. Ha! Open mouth, insert foot...

Mind you, I haven't got an iPad yet, but it is tempting. I might pick up an older used one, just for what these programs can do. Admittedly, it doesn't do everything I want YET...

But who knows? That's the beauty of software.
