Funny, I've been running Debian since 2007. I mainly got hooked on their 'testing' branch since it is just "always up to date".

But I always get people looking over my shoulder and asking "what the heck is 'iceweasel'. To which I explain the whole issue of Debian was distributing a patched version of Firefox with their OS back in ~2007 era and Mozilla, for trademark reasons, said you can't modify the browser and still distribute it with the official logos and name. Which lead to Iceweasel... but then a few years later Mozilla changed the license terms so now I guess here we are....
