I think the included warranty varies by country. Some countries have required minimums for warranties. In Canada, it comes with a 1-year warranty. The 4 year I bought was a depot warranty (aka take it to the nearest certified repair center or mail it in). The premium "we'll come fix it" warranty does exist but it's like 50-80% more expensive I think. I didn't feel the need for it.

In fact, I probably wouldn't have gotten the extended warranty at all if it wasn't so cheap. I feel comfortable with the build quality of the device that I'd risk it and possibly do repairs myself.
