I'm actually a Linux user and like to hear people's opinion on this controversial issue. (Linux or Windows)
I'm sure many people have had about Linux but most get scared of the name. They believe it's an operatiing system that's meant for the gurus so to say.
But I'm happy to tell you that Linux is actually making a more interactive interface operating system system with nice colours, quite flexible to use (you can play your DVD, VCD, MP3, audio CDs, games, run Microsoft Word / Open Office, etc.) and never have to worry about viruses ever again.
Imagine, many programmers now write programmes for Linux, e.g. Yahoo Messenger for Linux, SQL, Maya, and lots more. Guys why not give it a try? I've worked with many versions: Redhat, Knoppix, Mandrake, etc but I would say Mandrake Linux 10 is a good one to start with.
