If it doesn't have airy mids and/or sparkly highs, what effin' good is it? Srsly, though, it'd be pretty bitchin' to have a version of the recorder you can just stick in your signal path using standard 1/4" cables. And you'd probably have better margins, since you wouldn't have the extra packaging and materials and labor associated with permanently attaching the cables. And you could employ a form-factor that affords a little better user-interface, since you're not constrained quite so rigorously by the 3/4" cylinder that thing is in.
But it is a neat idea, and even a useful one.
