I suppose that explains why Lenovo is the most profitable pc manufacturer....

Cramming so much feture and performance at the price they are selling, something gotta give. Simple engineering really, the bigger they are the trickier the engineering for the casing. Lenove have spent so much on them innards there is not that much leftover to make a better casing. Reason why business grade laptops are a lot more expensive than consumer grades where more resources are directed towards protecting the system inside. With business grade machines you will just get so so performance but you will get lots of years out of them. Them higher grades Dell Precision cost a bomb.
