GM, Ford, or whoever has released a new model either. The most compelling reason for everyone to upgrade ended more than a decade ago. For the most part, the stuff works. If the new version enhanced the bottom line, that would be the reason to invest in the upgrade. If my workers become more productive with a tablet, that's a reason to invest. So far, I'm not seeing the advantage for more than 25 percent of businesses and government agencies to do so.
