Second-generation products tend to have most of the kinks worked out, though for some, the iPad 2 is exhibiting issues with the screen that have appeared in past Apple products.
One of those issues is light leaking from around the bezel into the display. A handful of threads on Apple's support forums (1,2), as well as a poll of users on Engadget, have called it out, with some taking photos that show light spreading out from one or more of the iPad 2's four screen edges. These leaks do not appear as focused light, but rather a band that's the most intense at the edge, and dissipates as it goes inward (as you can see in the picure at the right).
Another issue, as noted by MacRumors last night, is a patchy yellow discoloration, which may or may not be related to the light leaks. A similar issue affected some iPhone 4 owners shortly after the launch of that product, and was chalked up to the screen bonding agent from the phone's production still in the process of drying out.
From the look of various support and community forums, neither of these issues is widespread, though with the iPad 2 going on sale just last night, it's too early to make that call.
CNET has reached out to Apple about both issues to see if the gadget maker is providing any guidance.
