I only, within the last month, left my eight year old Nokia 2495 for something marginally newer (a samsung gravity t). the nokia still works flawlessly, but i was in the store to break my "family" plan into a pair of single-person ones, and it was a $10 piece after MIR.

there are two very handy features it has that my old one didn't: camera (picture taking & viewing), and a full, if small, slide-out qwerty keyboard.
