Windows 7 for work, Ubuntu (sometimes)
Windows Vista for personal

XP, 7even... Depends on the computer. At home I have XP and commander.

I'm using multiple os
For work - windows 7, ubuntu 11.04 and fedora 15
For Gaming - windows xp sp2

i love testing new operating systems and have recently installed meego and jolicloud

On my laptop:
Dual-boot Windows 7 Home and Ubuntu 10.10
Ubuntu for development / school work
Windows 7 for playing / internet explorer testing :P

On my desktop:
(Currently run a triple-boot, but am deleting 2 partitions for more room)
Linux (I forget what version/distro, but it's old) - Old developing, before laptop
Windows XP SPX(?) - Old gaming, before Win7
Windows 7 Ultimate - Gaming

I'm deleting both the linux and windows XP partitions on my desktop to make room for moar games. My Windows 7 has 3 gigs of free space left on it, on a 500GB hard drive >.<

I'm using windows xp since i began to have a computer.

Just windows, no need for any others, though I do want mac os

I am using Windows XP which is the best for me and easier to operate.
