I thnk that some folks decided a while ago, that if you add a laser to what-ever it is you are selling, youl'll sell more of them. I think it is the same marketing group that decided that if you make something out of a billet, and loudly say as much, you will sell more than the non-billet product. Interesting, but that falls into the "jut because you can, doesn't mean you should" catagory. On the other hand, give me 5% better gas mileage and I'll listen.
