The Serval WS is also more than twice the price of my Pangolin... and I had a one year warranty, so I'm not sure what you mean with lifetime support. As for the specs (i.e. the screen etc.), yeah, they are great. But the case is very poorly designed on my pang12, and gets bent out of shape, which can cause mechanical failure in the hinge, quite frequently, despite the aluminum chassis. My complaint is just that it is far from rugged, which is problematic for me, as I travel a lot with it. But your mileage may vary.
PS: one more thing that really bothers me is the known problem with the touchepad on the pang12, which regularly fails. Mine also came with a faulty motherboard, which suggest bad quality control. Over all, these issues have caused me to lose faith in System76 hardware.
