The new iPod nanos are exhibiting screen problems for a small subset of owners, whereby the screen doesn't appear to be completely level within the casing. More than a dozen people have reported the issue on Apple's Support forums, with most reports saying video appears tilted slightly to the left. Apple is replacing units that exhibit the problem, although judging by some anecdotal reports, entire batches at certain stores have the problem, making replacement a far from adequate solution. Fortunately, it appears as if it's possible to notice the issue with the nano inside the box. At least now we'll know what the problem is if we run into any gadget fans with crooked necks.
