My release-day iPad 2, which has been otherwise working perfectly, is now showing signs of screen image retention and burn in. Static items like the Safari URL bar and bright image boxes on grey backgrounds (eBay app) are causing - temporary so far - image ghosting on the display. Anyone else see this on their iPads? Two original iPads we have aren't showing anything of the sort. Think AppleCare would authorize a replacement? I may take it in this week to see if they will.
