Laptops also have in effect a cleaner power source with UPS built in so any power glitch's get filtered on a laptop as standard compared to a desktop.

Least I have found desktop's with a good quality PSU and UPS noticable more reliable than those without.

I've heard this theory before but never seen it substantiated. Do you have a link to any research or articles that explains how this works?

How it works? Laptops have a battery. Hence they are less likely to power off suddenly when mains voltage drops. And powering off suddenly increases the probability of some electronics in the system failing. No need to research, just simple electronics and logic.

Pull your laptops power cord out the wall, and plug it back in. Laptop unchanged. Dirty power supply, but laptop unaffected.
