A TV Screen tends to attract dust due to being ionically charged. This is annoying for those who watch -- the more they watch, the more the dust clouds up the picture. This is a slight relief for those who have the dusting, since dust that lands on the TV screen doesn't land on the more irregular, and more difficult to dust, surfaces.
I'm envisioning a strongly ionically charged wand that attracts most of the dust in a house, and is easy to clean with a rag, and an ionically charged duster, that sucks the dust up as if by vacuum. Oh yeah, nice and clean.
