This could be old news to many people but i was talking to an apple store manager today who informed me that the yellowing screens on the SR LED backlit macbook pro is currently being fixed by Apple. The reason that there are no MacBook Pro 15" model's currently at many Apple Stores is because in 2 weeks Apple are rolling out NEW MacBook pro's with all of the SR problems fixed on them (the manager said they have been backordered for a month). Obviously this will come as an annoyance to many people who have bought MBP's recently, however if you do find fault you can take them back and get them exchanged for a different one if you are unhappy. Those who are buying online and are experiencing extreme delays, this is why, apple do not want to sell you a defective model which they will ultimately have to replace at a later date. So any people, like me, who are looking to buy MacBook Pro's, stick around until Mid August when a new and improved shipment will be coming into stores thick and fast
