I did the same as you and migrated away. I was looking at the XPS and ended up going with the Razer Blade Stealth. What's actually surprised me most is how much I enjoy having a touch screen. I could see checking out the new surface pro 2 at some point now.

The other huge thing that surprised me was how easy development is becoming with the new Windows Linux Subsystem. The only thing i haven't gotten to play nicely with it is Postgres, but I just set it up in windows and have the wls connect to it and I'm on my way.
