Hmm... so much going on here, where to start?
Well, let's just start by reiterating that I've been a repair technician on the front lines for over a decade now. I dealt with customers, not theories (no disrespect to engineering students, you guys just don't get to see the real-world application).
The "only fails within 72 hours" myth is just that. Myth. only 5% of machines have a hardware failure "out of the box" (which is any time within the first 14 days, by industry standard).
However, I could corroborate (from personal experience as a technician)data published year after year by PC Magazine that the average failure rate for year 1 is about 11%, and grows quickly after that. Some manufacturers (ex: Dell) have a failure rate of 25% between years 1-2 (making the statistical 0-2 year failure rate 31%). And it grows basically exponentially after that.
Now, "failure" means any hardware failure... CPU fan, power supply, hard drive, what have you. far and away the most common failure is the hard drive, followed by the motherboard, optical drive, and power supply (other components rarely fail).
Now something else: I know a lot of you probably have built or self-built generic PCs. this is NOT the norm of American computing. The largest numbers of machines in service are Dell and HP. Both of these manufacturers use a lot of proprietary parts in their manufacturing process, which cost far more as repair/replacement parts than their generic counterparts.
Practical example from near the end of my last job (Feb 2006):
$600 HP machine, 15 months old. Outside of manufacturer's warranty. Power supply failure. Very common, as HP used to use 150W power supplies where most others would use 250W or higher. (They now use 180W and 200W for the same applications, so not really any better). this part originally was designed by eMachines as a proprietary form factor, that eventually became Micro-ATX. However, it also requires an HP mounting bracket because HP changed the form factor. Cost of power supply: $149.99 from HP (after middle-man markup, of course). Cost of labor: $99.99.
Cost of 3 year basic warranty on same machine: $179.99
In the cases of mom-n-pop generics where you have enough technical skill to replace your own parts, a warranty may not make sense. but take the other 95%+ of America into consideration (especially from the technician's point of view, not the salesman's) and it really gets to be clear why.
The other fun thing about computers is they tend to fail in clusters.
Practical example from my new job (around April of this year):
X client orders 1075 new Dell workstations. around 300 of them have their hard drives fail within 1 month. All drives are replaced and of those, another 12 have drives fail within another month.
That is a statistical aberration on the other side, which means somewhere else, someone is getting away with having a computer that statistically SHOULD break... well, NOT.
Statistics. It's not Math. It's English on Drugs.
