Congrats! I am also using Linux 'fulltime'. I've been using computers since MSX and finally abandoned Windows as my primary OS in 2005. At work, I always keep a Windows machine around since we have an AD domain and have to keep supporting it, but Linux is great, even more so in the last 5 years when games are running 'almost' effortlessly.
If I can make a suggestion, check how you can contribute to your favorite distro. I've been helping out on Debian's pt-br translation team and it's very satisfying. I strongly recommend it!
I think his post explain but does not justify de decision. This suddenly changes os RedHat are kind of unnerving.
