About to built a new computer box instead of buying off the shelf but want to abandon proprietary software and go completely open source. Been using Firefox for example and love it. Any open source operating system users out there, what are you using and how are you liking it? Pros? Cons? Just tired of Bill Gates always looking over my shoulder and routinely picking my pocket and Apple just hurts the wallet altogether. In doing some research I came across this 2008' piece and also this Linux based open source O/S. Thanks in advance for your ideas and experiences.
