It does much more than tell you where you've been. You can upload routes and times, training sessions (intervals, pacework etc etc) set zone limits, race virtual partners, or yourself on a previous run of the route. Also calculates height etc to give true distance and gradient. Keeps an accurate training log very simply. And so on.
Don't think they are exploiting. OK, the units aren't that cheap, but they are well designed and roubust, and the analysis software is free.
If you don't want the usb element, you can get a 105 - just GPS distance and stopwatch, as well as the training functions, or less than a decent dig watch. I have one I used to use as bike computer before I got me 305 and Edge.
I find they give structure to my training, and an addition point of interest, which is motivational.
