To me an extended warranty is about the person not the product. ;)
My brother just bought a new car and paid additionally for a full 7 year extended warranty. Not a chance I'd ever do that BUT he's a do nothing guy when it comes to cars - he knows how to drive one, put gas in it, and does get the oil changed when needed but other than that he doesn't want to know about how anything works and has zero interest in fixing anything himself. For a person like him an extended warranty probably makes sense but for those who have even a modicum of interest and willingness to deal with "issues" themselves an extended warranty IMO is a total waste of $$$$.
So what it comes down is - which type of person are you? :@
