I use a Dell XPS 13 (2014 edition) as my main dev machine with an i7, 512GB SSD and 8GB RAM.
It supports DisplayPort 1.2, which means I can Daisychain monitors. I plug in one DisplayPort cable and it connects to my 27" 1440p monitor and my 24" 1080p portrait monitor, giving me 3 separate displays to use.
