That's true, that would be pretty misleading if they already had LED backlighting, though I would think that if you had such a screen, it's a little early for an upgrade. How long has there been using LED backlighting in units cheap enough for mass consumption?

On a certain level, though, I feel like it's the consumer's duty to put in the research when spending the kind of money that these TVs cost. Or, at the very least, they seek out a trusted source who knows how these things work and has done the research for them (and no, I'm definitely not talking about some guy in a Best Buy uniform). If you're not going to do either of those things, and they're just going to walk into Coscto and pick up the first set at the size they want, then some of the blame falls on them.

Of course, if you're not going to do any amount of research into the product, chances are you're not the type of viewer who cares about the difference between edge-lit and full LED backlighting...
