* Apple MacBook - Nothing configurable. Expensive and not build to be repaired.
* Microsoft Surface - Much the same, but with Windows
* Lenovo Thinkpad - A little more configurable than a MacBook, and much better value, but still difficult to repair. Missing premium features like an Aluminium case.
* Dell XPS 13 - Much like the Lenovo, but the Linux option is nice.
If they pull this off, developers are going to love it. I really wish them the best.
My advice? Make sure it works _flawlessly_ with the top 3 Linux distributions.
