Or just don't have buyer's remorse and be satisfied with what you have.

This is just the downside to all technology. It can be a TV, sound system, phone, car, and even houses. It most cases (phones for example) you jump a generation or two before replacing your device. Typical lifespan (depending on the person) of cars is 5-10 years; I known there are a few people that lease and trade in every two years, but in my opinion that is just too damn expensive to keep doing.

At least with houses, unlike everything else in general, their value can appreciate and you can sell for more than you bought it for, especially if you made additions or upgrades that are desirable to new home owners.
