"That great high-definition television set you just bought may no longer be the best on the block. While most high-definition sets sold today have native screen resolutions that support the 720p high-def screen format (720 lines of progressive-scan video), a new contingent of 40-inch and larger sets offer native support for the 1080p format. The effect of the higher resolution is debatable now, but these sets will eventually mean improved pictures."
Once there is enough material out there to take advantage of this, THEN I will consider an upgrade.
