Why "Ubuntu"?

I was asked recently why I use "Ubuntu" instead of "Windows". 

I was casually playing around with "Ubuntu" since version 7.10 but what pushed me to seriously switch full-time was the anger over being forced to fork out money in a short span of time to upgrade to "Snow Leopard" and "Windows 7".

Version 8.04 LTS was so reliable for 3 years and there was no turning back.

There's also a trove of tools that are native to Linux that I use personally and for work. There's all sorts of "commandlinefu" that you can perform from the "Terminal".  

And yes... "Ubuntu" is free.
