I know. My nerd ego was nearly shattered...
I figured since I posted my present setup I'd go ahead and post my past one as well.
The MacBook Pro in the first image is coupled with a 24" ACD, an Intuos3 Anniversary Edition and a flimsy glass desk that cost a lot more than it was worth; I would've been more comfortable had I decided to work in a furnace. This is the MacBook Pro that the 2011 model replaced, the same one my wife is now using to prove she is much smarter than I am by acing her nuclear medicine exam right next to me.
The other shot is my PC setup, which is cheating, I know, but nearly the entirety of its life it was running a Hackintosh build the majority of the time it was powered on. The monitor is a 30" Dell 3007WFP-HC, keyboard and mouse is the G15/G9x combo. The PC, if anyone is interested, was an old C2D with SLI'd 8800GT's in a Coolermaster Wavemaster (Yellow) Case -- which served me well and was my last foray as a PC hardware junkie, before completely giving up on the platform for everything but the occasional game.
Some great setups above!
