Confused by all the changes Sony has been making to their Playstation 3 model line?

Chris Kohler made a handy Venn diagram of the PlayStation 3 models and their feature sets. Although I think he left out HDMI? Wasn't there something retarded where the cheaper PS3s don't have HDMI out? Because my new TV has two HDMI inputs gathering dust here. (Yes, I know there are now Xbox 360s with HDMI out.) Apart from that, it looks like the 'old' 20GB PS3 would be the ideal model for me.

You know, if I wanted one.
