Jeff Benjamin at iDownload blog takes a macro lens look at the screen resolutions of the new and old iPad screens.
Notice how you can barely make out any pixels on the new iPad even with the screen magnified many times over? Now look at the iPad 2. The difference, though predictable, is stunning when you compare the two devices side-by-side.
Personally I don’t think the video on iDownloadBlog’s site does the Retina display iPad justice.
