I'm thinking of getting a portable dvd player to watch while camping, a lot of times their is no wi-fi or cell service where I camp so I'm thinking this might be a good option to pass the time. I can get a sylvania 10" or 13.5" screen for about $85 to $125 with a 5hr. battery. Don't know much about other possible ways to watch dvd's so does this sound like a good idea or a waste of money? I don't have a laptop on the road just a i phone.
