You forgot one
OS/2, or eComStation (same thing, different vendor). For most of what nightowl does, it can provide software; mozilla for web surfing, pmmail for mail, lotus smartsuite for word processor/spreadsheet etc. There are very good tools available for monitoring the system if you find you're having a problem, and it runs well on older hardware. It has good system basics (kernel, drivers), but is not so good on supporting everything-under-the-sun like Windows does; for example, you have to shop carefully for a printer, make sure you buy a real modem and not a winmodem, usb device support is spotty (we're at the point now that most cameras will work, but most scanners won't yet), etc.
