I completely agree and I have an LG panel and have had this rMBP since July 2012.
It's superb. Screen is amazing and I own a quad-core Mac Mini+27" Cinema and have basically stopped using that since the start of the year. The 15" rMBP is that good.
There's some ghosting on the screen, but you only see it if you go *looking* for it. And herein lies the problem. People are just too fussy and expect absolute perfection.
We sell computer software all around the world. We have stores in the US, Canada, UK, Australia, Sweden, Ireland and Netherlands.
Where do you think we get the most complaints? From US customers. If they find even the slightest thing wrong with our software, they expect a full refund. Don't get a refund? They get their card company to charge back their money. Failing that, they consider a law suit.
And this is the problem. Expectations. Particularly in the States. They don't see the positives (the design, the superb screen), they see the negatives and go looking for them. When they find them, they get a real bee in their bonnet and expect a new machine, refunds and so on.
You are always going to get a pay off with a new design and, in my opinion, the positives far outweigh the negatives.
