Still not really something to "worry about" though, is it?
If there's a problem, there's a problem, regardless of which panel manufacturer you happen to end up with.
Just like the ghosting issues. Will never understand why people specifically go looking for it. If you notice it and it interferes with your enjoyment of your laptop then there's a problem. If you have to go hunting, then why is it an issue?
Because when you pay so much, you don't expect stupid issues like this. They are not minor.
Say you went to a really nice restaurant, and you found that 2 in 10 couples disliked their food so much they sent it back. You're telling me you wouldn't be worried that you might be that 2 in 10?
