I ordered my first ipad on day one from apple.com. SN was DLXFD. I noticed a bright spot by the home button immediately after turning it on. Searched the web and found this forum. I UPS'd the ipad back and received DLXFC in a brown box. Had a scratch on the back which I could live with but also had horrible bleed. I decided to hold onto it until Apple had some time to fix the issue. I just sent the ipad back on saturday and received a new brown box one today. SN is DLXFV. I do not see any bleed on this one while holding it under my desk, which is a good enough test for me. I think at this point they have some brown box, bleed free units sitting around for people with this complaint.
I do not believe this is an inherent property of lcd's. I checked my ipod touch, zero bleed. My panasonic and vizio tv's also do not have any bleed. The only time I've ever experienced such horrible bleed from a LCD is on my LG Octane cell phone, which is a free phone that I do not expect to be of the same quality as an apple product. I think Apple had a problem on the assembly line and was causing this, not the lcd panel suppliers. Just my opinion.
