Of course this is a different type of interface (and quite a cool one, much respect for this and their products - I talked with one of their folks at NAMM for a good bit) with a slightly different audience possibly - mains power required while still not charging the iOS device, adapter required for Lightning connection, no MIDI connection for your controller (but hey get BlueBoard anyway to go with it, I kid I kid), larger form factor, etc. But there's the great plusses of the multiple inputs, LEDs are definitely well-designed, metal casing IIRC, and more making it a bit of a different beast than the all-in-one super-portable unit we've put out there.
To me, they do seem like two pretty different devices but I obviously also have bias and some of the differences will be either dealbreakers or "meh" on either side of the equation, as always.
