It depends on what your trying to escape from and how plugged in you stay while escaping. Realistically, your not going to leave your phone home. But you can limit its use.Why am I going to the trail and the woods to escape yet staying plugged in via electronics.
My phone is used primarily for weather, GPS based guide book, photos, ebooks, clock and music. Being able to occasionally check email and be able to make travel arrangements is a bonus.
Just having up to date weather is worth whatever the price. Hum, should I get up now or wait until the rain stops? I think I'll check the radar...
