Prediction: By 2017, it will be worth $1,500.
Hmm. Sounds pretty optimistic. The original 5GB iPod from 2001 is starting to see an upturn in value, likely due to Steve Jobs' passing, but it seems to be capping out at under $1000, in the box with all accessories. That's basically 200% of the original cost over 10 years, or 20%/year. At that rate, you would be looking at $1000 in 2017, if collectors attach as much importance to the first iPhone as they did to the first iPod. One could argue that the first iPod was more of an historical turning point for Apple.
