Regardless, if a computer comes with a ridiculous 1 year warranty, that means the manufacturer does not trust that the computer will likely still function after one year. Otherwise surely they would try to gain your trust by guaranteeing (in many languages, the word "warranty" is the same as "to guarantee") its useful life with a warranty...
Add to that the fact that most modern electronic devices have almost no moving parts, and that they require no maintenance and that other than dropping them or submerging them in water (which have telltale signs), there is nothing a user can do to cause the machine to fail, so almost all faults are the manufacturer's fault and are a matter of bad luck to the user.
Add to that that anything you buy today will come with at the very minimum 2, but more commonly 3 years of warranty, be it a hairdryer, a memory card, a cheap mouse, a hard drive, a car (though most cars come with at least 3-4 years of warranty, with companies like Kia offering 7 years), or any computer not made by Apple (even cheap, unbranded ones).
If Apple makes a computer that is supposed to have a useful life of 3 years (that better be the case given the price and the upgrade cycle), then they should reflect that intention with a guarantee.
You can't spend money based on the HOPE that you will be lucky and that your machine will probably continue to work after 1 year.
There's no other good or service that I can think of that doesn't guarantee some sort of reasonable useful life for the thing you're paying money for.
A warranty means: You don't just buy a product and hope for the best, but rather you have a company's promise and guarantee that the product will have a useful life of a number of years. This means that manufacturers cannot just clunk together a machine from cheap parts that fail within a year, since a user cannot know how long the machine will last at the time of purchase. You can check if it works when you buy it, but you can't check if it will still work in 2 or 3 years because you don't have a time machine. But when the time comes, if you're out of warranty, it's too late to regret the purchase. That's why a warranty is important. 1 year is useless for a product that NO ONE intends to replace on a yearly basis.
