I wasn't able to download it. Clicking the link on this page took me to the Software Centre saying "Not Found - There isn’t a software package called “steam” in your current software sources.". So I go to the main landing page of the Software Centre and find a link to Steam there. There is a banner saying "Free" with a button "Buy" next to it. I click it and it asks me to log into to some sort of payment service...

I love linux and Ubuntu but this is the kind of thing that I am starting to get sick of having to deal with. Can't I just use apt-get?
