Since the invention of the laptop these have always been repairable, and it has customarily been simple to replace batteries and harddrives, or even to add in more RAM at times. The death knell for responsible laptops was when Apple eliminated the battery cover and glued the case together. Somewhat scary since in the previous model we had several coworkers with failing batteries that would swell to double their volume and push the battery cover off...
Ten years ago just about every device you could purchase had some repairable parts in it, all of which could either be fixed by the user or with a technician, without having to mail it back to the manufacturer. PCs, refrigerators, televisions, microwave ovens, autos, cellular phones, laptops, pagers, wrist watches, etc. Ten years ago there wasn't anything that worked with a battery that could not also have the battery replaced.
