I purchased a 17" Macbook Pro nearly 3 years ago to the tune of nearly $3,000. Recently, the battery overheated and burst. I had it wedged into the back seat of my car (in a protective soft case) with a bunch of stuff & it probably overheated. Because the battery expanded by about an inch, it put force on the aluminum chassis and bent the case of the computer. I purchased another battery from a supplier & didn't think much about it, deciding to just live with the bent case. I mentioned the situation to an Apple employee at an Apple store & they said Apple would stand behind the malfunction.
Three months later, I brought the machine to the local Genius Bar, and they took it from me no questions asked. A week later, I have it back in my hands. Apple replaced the chassis top and bottom, the screen, the trackpad, the keyboard and several internal components, including the optical drive. It was FEDEX'd to me overnight.
I'm completely blown away by this company's customer service policies. I've owned Macs since 1984 and plan to keep overpaying for the luxury of owning some of the finest pieces of craftsmanship available.
Amazing thing is... I could probably eBay this 3 year old machine for $1500 or more right now & upgrade to the latest & greatest. Naw.... this one is doing just fine so I'll keep it for another couple years
