Well, there are two parts to weight: one is, yes, the better quality parts you use, the heavier it becomes, and two, companies do know that perception and they intentionally avoid using lighter materials and make enclosures heavier using steel instead of aluminum, or use thicker gauge sheet metal where half would suffice. Because customer often associates heavy with quality.

Have been watching this for a long time in several companies including those I worked or am working for.
