That's what I was saying about the razr, etc. Quite a few years before the I phone, blue tooth, cameras,mp3, and phone. The tattoo industry is no different than the car industry or anything else like that. you have Chevy vs Ford, Mercedes vs bmw, Toyota vs Honda,etc. Same type drive systems, with subtle differences that make them stand apart from each other. It's no different with tattoo machines, and supplies, etc. Time will tell what stays and what goes, and it will evolve based on what works and what doesn't, simple as that.
