Counterpoint: I know plenty of happy developers that own multiple Nexus and Pixel products, without bagging them. Engineers want good hardware and many are willing to pay for quality.
> As for the so-called "Apple tax"
For as close to equivalent as I could get (specification, reliability, etc) the equivalent Apple cost 50% more than the XPS 15. Paying 50% extra for an OS I don't need makes no sense for my situation. Paying for an unused Windows license for the XPS was unavoidable (I have our own licenses for the Windows VMs we need for testing).
> It's clearly not trivial [to make a laptop better than Dell or Apple]
The Google hardware I have experienced has mostly impressed me (even if third party, they have mostly enforced quality constraints). Although I have owned a Nexus with a design flaw, I would consider buying a Pixel (although at present I find the Nokia gives me better bang for my hard earned buck).
