My Original GB has lines too. It's not a huge deal. By that I mean that it doesn't mean the GB will die altogether soon. It's just because the ribbon connector that controls the pixels vertically comes loose. It can be fixed fairly easily with a soldering iron but I don't have one of those...
This winter was awful. Our local ski place only got to open two slopes because of all the rain that kept destroying everything. Such a bummer. Oh well, snowboarding is fun no matter the conditions when you're with friends :)
