I read the article and noticed that it wasn't shock proof or waterproof. That doesn't mean that it still isn't their intended audience. They can have their waterproof shock proof tablet to use out in the field all the time but a phone with that long of talk time and standby time at base camp is huge and a life safer if their other equipment failed or lost power. Hell, the benefit of the battery with cellular or satellite tethering lasting extra long in the field where there is no internet is huge.As usual folks don't read the article before commenting, this is neither water nor shockproof so quite useless for the purposes above. Now if it were made more rugged you can bet lots of folks would be interested.
Please don't just ASSUME things because it tends to make an ASS out of U and ME.
