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.
