We still only get 1 year of warranty though?
I get 2 years but that's only if you are a consumer and bought it in Portugal. And I can tell you that it get's expensive for a brand to constantly replace some products. Like when you get a clearance sale and it breaks after 1 year and a half, you sent it to warranty and it no longer exists either they give you a better model or return your money.
An example: cellphones are much affected by this since they are very prone to problems (specially software problems), Nokia for example even claims the phone was exposed to water when it wasn't just to get rid of the responsibility (even when it's a software bug!), but some people just damage their phones in the hope of getting a new one.
Another expensive example: every time my mp3 player dies (sony) they give me a brand new one and the warranty resets, so you get 2 years from the day you get the replacement.
That has to be expensive.
Since Apple is very strict with warranties I don't really know (but they won't replace a product unless there's no other way and the warranty won't get extended).
