"Of course, ITBs are today's "something different"-and likewise, we all want it (or at least would give it a try for the right price). Our bet is that once knowledge is shared among tuners of the best way to use them, ITBs won't be such a thing of mystery; prices will fall and they'll gradually become less scary, albeit less "cool." At least, until the next new thing gets abused enough to take its place in the shadows."
Last bit sums it up IMO. Has NOTHING to do with making power... It is all about the "hey look at me" factor.
