At full brightness the flickering is barely noticeable unless you really tried to look hard for it but you can also see it on website backgrounds with lots of lines, such as the left sidebar on http://gizmodo.com . Also, when the backlight dims after being left alone, the backlight flickers for a couple of minutes and then disappears. I have had this macbook for a bit more than 2 weeks. Should I send it in for a repair/replacement?
