TrustedReviews posted a review of the Sony VAIO VGN-TX1XP laptop

But there’s more to the screen on the TX1XP than first meets the eye - Sony has equipped it with LED backlights, instead of the more common fluorescent light sources. There are a few key advantages to LED backlighting with some more important than others on a device like this. First up, an LED backlight gives you a wider colour gamut, making it ideal for image editing - now this is a big bonus for a large desktop screen like the NEC SpectraView LCD2180 LED Backlight (I have one of these in the lab right now, so expect a review soon), but how important it will be on an 11.1in display is debatable.
