They do put a lot of care into their products, but their cult following does seem to play an important part in protecting their image. There's another thread on the front page of HN where people are describing how their Apple laptop power adapters burst into flames.
I am typing this on an iPad that periodically loses its wifi connection. Googling the problem yields dozens of complaints about this issue. Apple supporters on these forums blame wifi routers, even though the iPad is the only device with these issues.
I like the App Store, but, by default, I can't buy games on my iPad - why? Because I live in South Africa, and unlike every other device manufacturer with an app store here Apple hasn't applied for self rating games, which, according to most sources, is a straightforward process. Again, Apple and its supporters don't bother mentioning this little detail.
Apple does put a lot of care into their devices, but I also think there is a tendency to deny issues, to brush them over and to rely on the cult to impart an aura of invincibility.
