"The commercials' characters are personifications of the computers... not owners."
Oh bull! Who on earth is going to believe that interpretation? You surprise me at times with your partisanship.
Who on earth? How about any body with a clue?
Notice the captions.
According to your interpretation, Avenir, in the commercial called "Surgery," the OWNER of the PC is having surgery to install a new processor, new graphics card, and more memory??? Or in the one called "Tech Support" it is the PC user that is having a WebCam taped to his head??? In "Accident" it was the USER that was pulled off the table by someone tripping over his power cable. RIGHT. Sure.
