Gotta agree with Emma here. If the person traversing Everest has little or no real experience with that type of climbing, it’s stupid. If a person backs off a cliff whilst taking a selfie....it’s stupid.
We never cared much about cellphones until we starting RVing several years ago. A cellphone is almost a necessity when you're away from home for weeks at a time, plus the hot-spot connectivity is great for internet/email access. We have iPhones though they are not the latest and greatest, and we still have our land line that is bundled with internet and cable. I much prefer to talk on the land line phone, and the most use my cell gets is the Kindle app so I can read anywhere without lugging another device or book around.
