What's the difference between the 42-, 46-, and 50-inch version of the 'same' TV? Not much.
(Credit: Panasonic)As you may have noticed, I've recently changed the way I do reviews of HDTVs at CNET. I call the change "series reviews," and I'm curious to know what you think. But first I'll tell you why I did it.
Individual HDTVs are typically members of a series, where the only difference on the specification sheet between various models in a manufacturer's lineup is screen size. A great example is the Panasonic TC-PS1 series, which includes six screen sizes at various price points, from 42 to 65 inches. In my review of the TC-PS1 series, I only performed a hands-on evaluation of the 42-inch model. But I also posted the review to the 46-inch and the 50-inch model, making sure to explain that I didn't actually perform hands-on evaluations of them.
Previously, we would review one screen size in a series and post a simple note (example), not a review, on the other screen sizes, basically saying that you could expect similar picture quality from all screen sizes in the series.
Why the change?...
