One problem with laptops is that since they can't handle the heat, they run
slower than desktops with the same processor. I have a fairly fast duocore
laptop but it's dead in the water compared to my desktops.

maybe yours is like that but that's definitely *not* true for all
laptops.

But when a laptop with new core i5/7 mobile processor gets gunked up
with dust - as they all do,

maybe yours get that way. mine certainly don't.

i recently opened one of my laptops to swap a hard drive and there was
no dust or gunk. it's 4 years old, which is plenty of time for that to
happen.
