How practicle is it to use a Plasma screen for every day use, i.e. watching TV on it? I was very impressed with the Fujitsu PDS4233 and was thinking about going for it insted of a 36inch TV. My ownly concern is how practicle it will be as I watch a lot of TV as well as a lot of DVD's. I guess I would need to invest in an external tuner (one with teletext if such things exist!). Any views of recommendations, THanks, Glenn.
