Pretty obvious that Apple is running into supply chain issues with the current demand, adverse world events, etc. The article makes mention of some complaining about light bleed, but I would venture to say that this addition to Apple's LCD suppliers is not in response to that.
I understand the optimism, but with the technology and price point, you simply aren't going to get anything different. Not sure why it doesn't sink in with most that this 'issue' existed with the iPad 1 as well. Why would you think Apple is suddenly giving it credence after the iPad 2 has already been launched? Common sense would tell you that they wouldn't, as the demand is so high for the device, any light bleed from the 1st or 2nd generations is a non-issue in the overall scheme of things.
The fact of the matter is that majority of consumers really don't care.
Funny thing, tho... I don't remember seeing any threads about backlight bleed with the iPad 1. I also don't remember reading any complaints about bleeding as well, even though the first iPad was also used in the dark. So with all the complaints we are seeing today, how can you say that the same issue existed with the iPad 1? It may have existed, yes, but not to this extent. Given the number of complaints w/ iPad 2, it's fair to say the issue is far more widespread with iPad 2 than it was with iPad 1.
