Why Ubuntu rather than Windows

Ubuntu Lucid is one of my new ultimate operating system choice and trust me it is not for the faint of heart. Though I have not left Windows completely (I usually have to switch to it to play games and do some work) but after much determination and struggle I have managed to adapt myself in the Linux environment and it is very cool and challenging.
