I have a Lenovo Thinkpad W550s (i7-5500U and 16GB of RAM). I dock it and use two 1920x1080 monitors (and not the monitor on the computer) with a bluetooth mouse and a Microsoft ergonomic keyboard. It's provided by my company's IT department who keeps up security, though I do much of my development in an Ubuntu VM. If I was providing my own machine, I'd probably do similarly but use Ubuntu as my main OS and have Windows for the few Windows-specific tools I need.
