I had the pleasure to see this unit and play with it. Samyo showed it to me.
It's a nice unit and pretty small. Nice gadget to have if you have spare cash.

Do I think we need a special power supply for rotaries? Maybe not.
Conventional units are doing the job just fine.

I personally prefer straight forward power units.
Something that makes me do less work rather than make me do more work.

The least buttons I need to press the better.
