The advances are slowing, but each generation is still slightly better than before. I do look forward to the day that the new tech is like a new car: just a different fender. For now, I am addicted to having the "best in class". Oddly, this time I waited until MWC to see the new HTC One before I settled on the Nexus 6. I may last me two years before I feel the need to upgrade. Maybe.
