What is your Operating System?

I use windows XP. This is flexible one and also a well know operating system.

I'm using Windows XP Pro SP2. never tried other OS like Linux before. Will just use the built in OS that comes with the computer hehe.

I use Windows Vista, and I'm really not diggin' it. I've liked my other Windows programs way better in the past. I guess either people love Vista or they hate it, and I'm defiantly not on the love boat over here.

I use Wndows XP and it works great for me! Never had any problems at all.

I use Windows XP for my personal use... I'm a little sceptical to use Vista, yet. But I study computer sience so there are projects that required use of linux. So I have non install version of linux called Knopix or something like that. It's easier that way. My friend once instaled two OS on her hard drive and couldn't log on for two weeks xP

I use Windows XP. I use it because its fast and efficient for my online or offline activities. I do use Red Hat Linux in my college for shell programming. But for majority of the work its XP

I am using Windows Vista Home Edition. and it is really great.

windows since I'm more familiar with it but I'm planning to have a linux OS for my other computer but I need to learn more about the OS before I install in on my computer;0

Windows xp and Mac

I know only windows platform. However, looking forward to migrate to linux since its free.

Windows Xp and Ubuntu

Xp because it came with the computer. I don't think most people really choose. They just use what came with their system.
