I wish I made a yearly habit of this, documenting my front end work flow: both hardware and software wise over the years.
Historically its largely been determined by place of my employment. When I worked for a university bookstore, my workflow was pretty basic. I was given sort of AMD WinXP config with Dreamweaver / Photoshop in 2010 followed by some sort of awful energy drink.. My job after that was an 21 inch iMac in 2012 with Coda / Photoshop / VMware / iOS simulator, and with some sort of tea or energy drink.
Over time my workflow has expanded, smaller computer but bigger displays and more devices, and more software and straight coffee has replaced all inferior beverages.
