In a previous post, I shared the general observation that the POS software market has reached near-full saturation: nearly every restaurant has a POS system. I described how the nature of the POS market-which is still strong-has shifted from new installations to replacements and enhancements. Something else has shifted along with it: you buy differently than you used to. You've become far more strategic, far more knowledgeable, and far more problem-oriented than you were, say, 15 years ago.
