My laptop repair count went way down (from 3 a year to one every 5 years) once chips no longer had the ability to become unseated. I think it is a reliability boon and a repair cost savings, not an up-front cost savings.
Working IT consulting for about 5 years, I have never experienced an end user with an unseated chip, not even on my personal products.
Irony, of all laptop I have owned, the most problematic was the Apple PowerBook. It's screen became defected a month or two after the warranty ended. The external VGA connection had issues and might require a couple restarts to get a signal. It could barely be used as a desktop computer. Even though I used it to write my first production software solution. It was ditched as soon as financially possible.
