Um... those are all articles for iPhones. What does that have to do with iPads?
People have been claiming the issue has never been due to glue. If you look at the iFixit article on the new iPad, they specifically mention that the same adhesive is used on the new iPad as the iPad 2. And a simple Google search would have pulled up more links than just those, so I'm not sure how people can claim the issue has never existed.
