In the world of software, you can just make a version of your product called
“Professional" and another version called "Home” with some inconsequential
differences, and hope that the corporate purchasers (again, the people who are
not spending their own money) will be too embarassed at the thought of using
"Windows XP Home Edition" at work and they'll buy the Pro edition. Home Edition
at work? Somehow that feels like coming to work in your pyjamas! Ick!
