Re: Why Ubuntu
err.. if you don’t like the windows manager, you can install a different one. you aren’t locked in to the default wm. 
linux is a serious commitment. it is awesome if you are a serious geek. think raspberry pi to customizing your wireless router to do all kinds of funky stuff.
if you are primarily using your comp for apple or microsoft apps as most average people are (nothing wrong with that), it is clearly a poor choice.
and stupid name? not at all.
