And what software?

I use Solidworks as my primary CAD program and run it on a 13" MacBook Air through Parallels. If a design is exclusively going to be laser cut I find putting it together in Illustrator to be simpler than Solidworks, especially for making reference marks, etching decorative elements, and making repeated hole patterns. I use Cura for slicing 3D models, Sublime Text 2 for editing code, and Arduinos or Teensysfor making stuff go.
