I'll add to the chorus regarding the W5xx series. I have a W510 here that is 2 years old, and has been used heavily all that time. I also have a W520 that is 1 year old, similarly used, and has also traveled overseas a dozen times. No problems with either (both used for various Linux distros). Prior to Lenovo owning the brand, I owned IBM ThinkPads for years. I can testify to over over 15 years of their reliability.
