We have three laptops in the family unit, two HPs and one Dell. To me, the build quality on the HPs is much superior to the Dell. The Dell keyboard feels like a trampoline, while the HP keyboards are nice and solid. When you open the hinge for the screen on the Dell, it squeaks and binds, like a bad door.
I understand Dell, searching for a new market segment, will soon bring out the "Dell Dementia" computer. The hard disk will have very good, rock solid long term storage capability, but the short term ram will regularly fail and the same data will have to be inputted over and over.
