My flip phone mostly doesn't work around here, so although I take it with me (it is my watch), I seldom turn it on, which shows how much I care about time when I am on the boat. I do take my netbook primarily because I use it as an e-reader and often do a bit of writing on the boat. I also use it as as a back up plotter. No AIS and most of the time the VHF is off (it is down below and you can't hear it on deck. If the coasties are around I turn the hand held on to 16. Mostly I am unplugged when on the boat
