Got back last week from a 5 day trip in the smokies (where it rained incessantly). Got up to Mt. Cammerer for the third time... no visibility again! (1st time heavy snow, 2nd time monsoon style rain, this time dense fog that rolled in about a half hour before we got to the top).
I took my phone with me and really enjoyed having it. I have a galaxy s3 that I supplemented with a 4200 mAH battery ($20 on amazon). It remained turned off in my pack for most of the trip, but I would get it out and use it at rest breaks, campsites and nice views.
What I used it for:
camera (not much of a shutterbug, so this sufficed for me)
video camera (i'm surprised how much I am enjoying watching the videos I took)
weather reports (we could occasionally get 1x/3g signal when we were high up)
books (finished most of House of Suns by Alastair Reynolds and got a little bible study in using the kindle app)
altimiter (the gs3 has a barometer built in, so I played around with it... not very practical when leaving the phone off most of the time.)
text and phone (my wife and kids appreciated me checking in with them when I could)
I still had about 40% of my battery left at the end of the trip. And while this saved me weight (over carrying a camera, paperback & a small bible, or my kindle touch), I still treated it like a non essential luxury item since I wasn't using the phone for navigation.
I have been really happy with the 4.8" screen size on the gs3. It has replaced my kindle touch. I have read through several books on it, and while the screen is not as good as the e-ink on the touch, I have been fine with its quality. That said, I was not happy using the kindle app on my htc incredible (3.5" screen) due to the smaller screen size.
Does anyone know of any good first aid books that are well suited to the kindle app?
