One of the side-effects of developing software for a variety of different platforms is the need to use multiple desktop platforms for development and testing. My virtualisation platform is old school: a swivel chair.
All of the 3 major desktop platforms get equal facetime, although admittedly the Windows box is closest to the actual window. There may also be a PlayStation hiding in this picture somewhere (not labelled).
Nice set up! i like how your office space looks like it came out from the matrix minus all the excessive wires
