I'm an infosec guy, and I use a 13" retina MacBook Pro. Unfortunately my work laptop is different, but for outside of work (security is my hobby as well as my work), the MacBook does exactly what I need. Long battery life, great build quality, and the screen is amazing for reading a lot.

I'm not a fan of Apple, but when I was looking through my options while shopping for a new laptop recently, there was nothing else that seemed like it wasn't a compromise for the same price.
