I went a couple days ago, they replaced it in-store without asking a question. I went in, told them i had the cracks and that I did a little research online (actually just these forums) and told them it must be a common problem. The replaced the whole top, plastic, keyboard and trackpad. It's great! And it only took them about 30 minutes, which was good because I was afraid they were going to have to ship it to California.
