Mine is three years old. (Must admit that I'm hard on my computers, but slow to learn lessons. I'd bought a succession of HP laptops that often spent weeks at their service center and needed to be replaced every year to 18 months. Finally got wise and bought a Dell with the extended in-home warranty. The hard drive died on me in the summer of 2012--got repaired in my living room the next day--but it's otherwise been a great machine. I'm now a Dell convert.)
