Flat Screen TVs--Nonremovable Fixtures?

New technologies sometimes raise interesting issues and the fate of flat screen televisions in a real estate transaction can be controversial.  Unlike appliances, light fixtures and window treatments, mounted flat-screen televisions and their hardware are not part of the traditional boilerplate language for items that automatically come with the real estate.

It's always clear that artwork, although hanging on the wall, does not remain with the property.  Some say flat screen televisions are like a picture, and definitely the seller's property.  Others say the wall mounted brackets make them a fixture, and definitely the buyer's property.
