14 years ago, I had the HC1000 which I paid a ton for at the time. The HC800 blew it away when it came out, followed by the EA5 and now the CORE. HA technology and equipment have evolved to a whole new world over the past 14 years and the C4 organization, hardware and software has evolved from essentially a startup. While I do expect device EOL will always be a risk in technology, my guess is we will begin to see longer equipment life as C4 continues to mature. At the same time, I expect we will see an acceleration in system capabilities that will require equipment updates if we as users chose to adopt. That said, there is a price to be paid if you want to keep any product platform up to date on latest technology - whether that is the latest cell phone, latest smart watch, latest car, latest tv, or you name it. Heck, I now have to pay an annual fee to keep features in my car up to date.
