I got two years on-site for a XPS 13 (9343) dev edition for not many €s at all. One year is standard I think, I paid for an extra one. Screen got some wonky pixels in that time-frame but it wasn't until the power brick started acting up that I called Dell. They did make triply sure that a house call was necessary to make sure that the engineer wouldn't be wasting their time. Friendly guy showed up who used to work servicing mainframes and miniframes until that work dried up. Took the machine apart, swapped in a new screen, gave me a new power brick and went on his way.
