Purchasing computers second hand is fine so long as the software that's on it comes with the original discs and a proper activation key; again, a lot of sellers load computers with software that they retain the original discs and activation key / serial numbers for so it, too, is an illegal sale; there may be an argument that this software is installed for demonstration purposes, but we all know it's just there to entice buyers and the intent is that the buyer will keep the pirated software and use it. Such unlicenced software should be erased by the buyer otherwise they are effectively using pirated software which is classed as stealing.
There's no excuse with all the excellent free Open Source software currently available; Open Office rivals Microsoft Office for features and compatibility, GIMP and Inkscape are very good drawing / design applications, and there's a plethora of other popular free programs for just about any purpose. If someone genuinely just wanted to show off what a machine can do then there's plenty of free and legal ways to do it, pre-installing a suite of useful Open Source software for productivity is the way to go.
