Hi all,
I am using Ubuntu and Windows 7 in my PC as well as Laptop Respectively, what about yours please discuss here.
Windows 7 all the way!

Primarily Vista Ultimate.
I'm still using Windows XP Home SP3...

Hi,
Right now I am using Windows 7.Because Windows 7 is a vast improvement from Vista as it takes up much less ram and has other optimizations such as fast booting times. I recommend Windows 7, and if you really don't want vista and don't want to wait for the final version of Windows 7, you can download a copy of the Release Candidate from the Microsoft website for free and use it up till June of 2010. I am working with the Release Candidate right now and so far I have absolutely no complaints, considering Im a heavy computer use with advanced software.
XP home, and a little Vista on the side...
XP is beast but i still have to try W7
