Totally fair argument, many windows programmes do not run on ubuntu. But on the other hand, plenty of windows programmes run under the windows emulator (called wine through ubuntu)

It's really worth the effort, I use dual boot and reserve windows only when I need to run windows programmes that do not run well under linux' windows emulator. I boot on windows on average once or twice a week.

It is really worth the try, I enjoy computers far more under the Ubuntu linux distribution
