Dell has updated their 20.1-inch 2007WFP LCD display without much advertising. All they have done is posted a picture of the updated display at their site.
The changes include a complete redesign on the display, a 9-in-2 Multimedia Card Reader and a new set of the component inputs.
According to me you will get the older one if you order right now. I don't know why they didn't tell it in a release, may be they are not satisfied with the display and want to remain silent on it for some time...!
Rest all the features remain same. I think they should have added HDMI input in the upgraded display, that would have gone for some advertising then...!
