all the people that i know that own touches INCLUDING myself dont have screen protectors, just because they take away from the "touch"perspective of it....that being said i have never seen one of my friends have their screens scratch, its very hard to do and cannot be done easily
ok, I think I'm probably going to get a video. I have an old ipod right now, and it costs $30 to replace battery, but It seems like used videos go for about 50-100.
