True Sniffdog, buy you can use it for uploading/download/seeding. Just like Windows.
Yes it may be more advanced and less user friendly for people who are only used to use Windows. And to run specific Windows applications, you can always use Wine.

Yeah, if he only wants Windows and doesn't know how to use Ubuntu, than Windows is the way to go.
But I see it as a cheaper alternative and Ubuntu isn't that hard to use. But yeah if you are used to Windows and don't want it more complicated, stick with Windows.
