Legit Reviews reports buyers of Apple's new iPad are suffering from a problem similar to an issue that dogged the iPhone 4S's Retina display: a strong yellow tint.
iPhone 4S models rolling off the production line after October 2010 had a noticeable yellow tint to them. These screens had whites that were beyond what could be considered 'warm', with less vibrant colours, so much so, that some were nearly washed out. It appears that the same phenomenon has hit the new iPad. This problem is also being report on forums, such as those of Ars Technica. The picture below, shown on the forum, shows the problem quite clearly. Prospective buyers therefore may want to hold off purchase until this problem has been ironed out.
