OS

Microsoft Windows - Used in over 90% of workplaces in the UK, this is what drives your PC. I have extensive experience in most versions of Windows, including 3.1x, 95, 98 (and SE), ME, NT 4 Workstation, 2000 Professional, XP, Vista and 7.

Apple Macintosh - The alternative OS especially amongst designers. Have experience in Mac OS 9 and X while producing cover CDs for MacUser, PC Pro and Computer Shopper.

UNIX/LINUX - The choice of the academic demographic who use the power of UNIX/LINUX to run thin-client workstations or for programming and more.
