Internal computer parts are not even close to comparable to a tire. A more reasonable comparison would be a clutch, which you'd expect to last more than a year if treated properly.
eh, I had a wheel bearing go bad on a brand new car after 8k miles.
The model/make reviewed excellently, and is still considered a great choice. Two years later, it's been reliable and gets us from point A to point B affordably.
Especially when you are not the one who manufactured the item, but get the blame for it's failure (Hitachi hard drives in Dell computers... Takata airbags in Toyota cars...)
