Either you can handle the fact that technology gets obsolete rather quickly these days, or it bothers you. Typically, the bothering occurs after the new OS installs itself on your old gizmo.
Yesterday I found an iPhone 5 in the street. I extracted the intact logic board form the battered case and handed it to my son. He asked for an older cell phone for comparison. So I got out a 1985 Motorola cell phone electronics package (the size of a standard red brick) and handed it to him.
You can guess where this is heading. We looked at where the factors of a million of technology improvement came into play on the Apple phone.
