New OS

Logged and locked to new operating system. Ubuntu 9. Has some cool features and few drawbacks. Only major thing that will always be missed on lnux based OSs is a class document processor like Microsoft Office 2007. Undoubtedly it is the most compelling feature that keeps windows OS running. For rest of the things there is 'Wine' emulator. :D
Highly customizable OS. Saves from the hastles of virus and anti-virus. Resource efficient. Dashing looks. And not to mention comes for free.
