Gecko, really, what colour is the sky on your planet?

Any consumer electronics product - cell phone, computer, GPSR, etc. - can be considered 'fully depreciated' after about 18 months. By this I mean the residual value of the object is pretty much nil after about 2 years, due to advances in technology.
The GPS V you bought still performed exactly as well on the day you sold it as it did on the day you bought it. In fact, it probably performed better 2 years later, as a result of system software updates and cartography updates. So, why did you get rid of it? It still worked perfectly.
If your response is "Well, I got rid of it because I wanted a newer model with more bells and whistles", then refer back to paragraph 1.
I change GPSR's pretty frequently, because I like to stay on top of that particular technology. Same with computers. So, I accept the fact that I have to take the depreciation hit anytime I trade up. On the other hand, I still use the Motorola cell phone I bought in 1998, because it does absolutely everything I want a cell phone to do just as well as the 2004 models (namely, make and receive telephone calls). The only thing that would get me upset about my cell phone would be if it broke, however, I suppose 6 years of service is fair enough out of a cell phone that cost $300 when new.
