I just got a 15" uMBP in the beginning of August and thus far I've only used if number of times but I can't help to baby it everytime I use it. I'm used to using PC's and Thinkpads that seem built like a tank so everytime I approach the beautiful aluminum MBP chassis I always think it's quite delicate. Has anyone tossed their uMBP around and still have it in good condition?
