Friend of mine bought a server box running Windows XP, he didn't realize it had an Apache application running on it full time, taking up all the memory. He had no use for it so I killed it. It came back. I uninstalled it. It reinstalled. I had to find the install files and kill THEM and everything referencing it to get it to die. Had that box running sweet, and then he just HAD to d/l a trial version of Vista, ran on dual boot. Thing is he didn't know how to boot back into XP when the trial locked him out. I fixed THAT, too. I'm no techy, but I tell you what, he finally got rid of that box and now owns a Mac. He would have seriously screwed up yet another Windows box, and I shudder to think what he would have done with a LINUX box! Each has their purpose, and certain users should use what works best for them.
I appreciate Jack saying, be thankful for the opposition, though. He kind of snuck that in there, didn't he? If people weren't unhappy with the bloated, fault-ridden unsecure releases of Windows, or with the high pricing of Macs we wouldn't have user-friendly Linux boxes.
