Got my first phone in 1998 - Nokia 5110, since then:
Siemens c35i, Nokia 7210, HTC Touch, Samsung Galaxy Note 2 which I use still today.
I never understoon the need to upgrade every year or even every two years, just to have the latest model. I upgrade only when the old one stops working or when new model offers some fundamental improvements like "colorful display" or "android operating system" :)
