UNIX and OS/2 are like New York and Los Angeles respectively. In New York and in UNIX they have a system for doing things, and it's surprisingly efficient once you figure it out, but it looks unfriendly to outsiders. Los Angeles and OS/2 are nice and polished and look good on the surface, but when you get there you find that nobody has been there very long and nobody can tell you whether things really work right or not.
