Anyone played with this or something like it?
It seems like it would be fun to have, and a good way to know where you are on a new mountain.
They are a really neat idea and I don't begrudge anyone who shells out and enjoys them. But I do agree the technology is not quite there yet for me personally to justify the cost. However, augmented-reality glasses are currently getting a big push, for example Google Glass, and its only a matter of time before the technology is good enough and ubiquitous enough to do some really cool things in our future googles- I mean goggles.
