Orange Gate is an issue only for serious photographers, for a normal user you won't find any impact. And in fact most laptops display orange-ish Red. If you want perfect reds you have to spend upwards of 1 lac for professional machines with Adobe RGB color gamut screens like Vaio Z, Dell precision M, Lenovo Thinkpad W series, Hp Elitebook etc.
For a normal consumer S15 and MBP notebooks have good enough screens even though they do not have high color gamut.
Watch this video from 5:00 onwards the Reds on the 2012 S15 compared with 2010? MBP.

If you read the Amazon reviews and other user reviews you will notice that most people are amazed by the screen. And at its price its easily the best screen you can get.
I'm not saying it doesn't have an issue with Reds, it does as its a fault with the LG IPS panel itself but its not so bad as to ruin your visual experience unless you are a professional photo editor. And overall its miles better than all other Win notebooks below 1 lac.
Also read this to learn more about the screen and also the OrangeGate issue.

Quote from the Anandtech Review
For less demanding users, your eyes will mostly adapt to what you see on the screen, so while red might look orange, orange will look like something else and it all (mostly) works out. I can immediately notice the lack in contrast on a laptop without running any specialized tests; for color accuracy, though, it’s something I generally notice only when there’s a reference point nearby.
