I ended up purchasing Dell XPS 15 today. In terms of battery life, build quality and power there isn't much else besides it that compares to Macbook Pro (at least not until Surface Book 2 comes out but then it'll be horribly expensive too). I think what you're talking about is the Dell XPS developer edition. I'm not even sure if Dell sells them anymore. You might just get the Windows 10 Home Edition and throw a Linux distro on it. At least that's my plan.
