I wrote an article about installing XBMC 2 and the experience I had upgrading to the new version of it. Maybe this can help someone out.
I'm obviously pretty new to this (you'll see from my post), so if you do stop by and check out my post, please feel free to give some helpful advise.
I tried documenting as well as a could what happened during the installation to give everyone an idea of everything I tried to get it working (which I finally did).
Anyway, now that I have XBMC 2 installed, it works great, I'd say almost flawlessly. I appreciate all the hard work that has went into this project.
