That's the price you pay for buying a car that is updated continuously rather than waiting until the next "model year". Would you rather that people who bought after you had to wait a certain number of months before getting LTE, even though Tesla was ready to start installing it earlier? Almost every one of us has a story of "If I had only waited X weeks I could have had...". For me two years ago it was parking sensors and folding side mirror. Just enjoy the car.
Couldn't agree more. It's so easy to get emotional about this. I wish I had many of the new features Tesla has introduced but I can't expect everything to be upgradable. Progress marches on and sometimes leaves older things behind. It's just the way things are, especially with advanced technologies.
