I want to get the top line 15 inch MBP, with the 2.3Ghz processor. I heard there are issues with screens and cases creaking and trackpad issues... I've return so many things in the past, I don't wanna keep doing it. I have terrible OCD when it comes to Apple products and I'd really rather not be the person who always returns their computer because it's not perfect, but I just need one that has a good screen, no creaking and no trackpad issues. And any other issue lol Should I buy now or should I wait for the next batch? Also, when will the next batch be coming out?
