My MBP is now 6 years old, still trying to get my employer to replace it. The only problems I had were the HDD going bad (I replaced it with SSD) and the trackpad no longer works (i spilled a drink on it once or twice). I also dropped is in the street a couple times which could have contributed to the HDD failure.
Overall I've never owned any other devices this long with continuous use. With all that being said they are going to need to change their approach on this issue or they risk damaging that support reputation.
I've had some terrible experience with Lenovo around 2010, so this may be hit or miss, but Apple is certainly not the only company that can provide decent service.
[Japan] One day the fan of my Latitude started making a clicking noise so I called the service, scheduled a visit for the next Saturday and got the fan replaced, even though the noise didn't occur when the serviceman was testing it. In the process of replacing the fan he noticed my case is missing two rubber feet and promised to send me a replacement. A week later I got a whole bottom part of the case in mail.
[Poland] My dad had some problems with BSODs on his Vostro and after a bit of back and forth with the service they replaced the whole motherboard for him. Almost 3 years into warranty, 1 month before it expired.
If I ever decide to go back to Windows or Linux I'm going with Dell and their NBD warranty.
I personally had the same experience as GP (but ages ago): Bought an iBook G3 that had multiple main board faults every few months (that was a problem of the whole series). In Germany you can get your money back if a product has the same fault multiple times (i.e. the manufacturer is unable to fix the issue). Both Apple and Gravis, the retailer, acted so horribly despite the perfectly clear law and a clear paper trail of the multiple defects that I had to hire a lawyer to get my money back. Of course I'll never buy anything Apple again - not because of the defects (as said, that can happen to every manufacturer) but rather because of the awful response.
This is our operations team's way of issuing karma for years of pain if that's any consolation :)
