Apple's awesome warranty service. My MacBook shuts down randomly after running CPU intense programs. And it has slight orange color at the hand rest. Before calling Apple Care, I did all the memory/battery resets but wouldn't work. I was able to schedule a pick up within 5 mins talking to representative. Box arrived next day. Overnight ship to KY, took a couple hours to get fixed, overnight back the same day it arrives. Now it runs like a charm. They are pretty efficient fixing bugs they already know.
