It takes either a bit of courage or a leap of faith to over write Windows on a machine. Once it has been done, you have NO regrets.I have been using Ubuntu for at least 7 years. I just replaced my computer in August and this was the first time I had to install Ubuntu myself, but I did it. I uninstalled Windows from it and am so glad I did that too. The old computer still had Windows partitioned off. I always regretted that because I never used it.
