I use Windows 2000, and will probably continue to use Windows. I'm looking forward to what Windows Vista will be like when it ships in late 2006.

Linux is all right, but there's very little on it that Windows can't already do.

I think that OS-X is all right, but Apple hardware is terrible. It's weak, it's expensive, it ships with a one-buttoned mouse, and the cases themselves look like a block of frozen milk.

So instead I use OS-X on my computer with PearPC. Pity it's so slow...
