Having just bought the Origin Bundle, I can officially say Origin is complete and utter shit.
As soon as I saw I needed to download a browser plugin to run BF3, I knew these guys were complete amateurs. I'll run a shitty version of Steam (called "Origin) reluctantly, but I'll be damned if I'm gonna load more and more shit I don't need.
I uninstalled Origin immediately. I just never give a shit, I have too many hobbies to begin with -- easy uninstall.
