No rest for the weary on the Apple LCD front -- hot the heels of reports that the 20-inch iMac's screen is less than impressive, word on the street (and Apple's support forums) is the iPod touch is having trouble displaying blacks correctly. Posters have described is everything from a "negative black effect" to "shimmering" to simply "washed-out." We're hearing that simply bringing a defective unit back to an Apple Store will result in an immediate swap, but it certainly looks like Steve was glossing over a detail or two when he said the touch had the "same screen" as the iPhone, eh?
