True, but even the FAA admits (in Kendel's link) that they can't completely do away with VOR service. There goal is to reduce service to a minimum (yet to be determined) by 2020. That means there will still be some "needed" VOR's beyond 2020. Personally, I'm still equipped for VOR and have GPS (which has failed me in the past). As long as VOR is still available, I will use it. No reason to remove a working system. I doubt that I will ever need to "upgrade" to ADS-B, anyway!
