Okay, it's got a cool name. That's what's great about it. Can you even do big plywood with it? It cannot replace a circular saw, as large sheets won't fit in there, plus I have a feeling it would be REALLY slow if you did want to cut something thick anyway.
Maybe it's just me, but whenever a product is offered for "Four easy payments of $xxx..." I get suspicious. Or when they show me all the old standby tools going into the trash. As if!
Professional, expensive, specific tools are the only way to go, imo. To each his own tho!
