This is why I take the "business laptop" thing with a grain of salt. Most "business laptops" these days are just the consumer laptop with a slightly component configuration: Xeon CPU, Quadro GPU, ECC RAM etc. I have a hard time buying that the build quality is particularly different. On the Assembly Line the workers or robots are just grabbing from a different supply bin.
XPS Precision is not a real Precision as it's used to be. It's the same XPS, but with pro graphics. Seems that was an Dell's experiment to name regular consumer laptops Precision and it doesn't seem to be a very successful experiment.
