From David HM Spector’s Unfinished Business Part 2: Closing the Circle (LinuxDevCenter: 7 July 2003):
The UNIX world is the result of natural evolution, not the outgrowth of a planned community. UNIX is a lot like New York City: dynamic, always reinventing itself, adapting to new needs and realities. Windows is a lot like Celebration, USA: static, a set piece of predictability, slow to provide new services and very resistant to change or difference of view or opinion.
