I think mines pre 2009, not sure though. I got it with Killzone 2 so when ever that came out and mine is sorta running outta space too. I think its an 80gig aswell and its the old fat model but not the one that has PS2 compatabililty and only has 2 USB ports. Any time I get a new game I have to delete a demo or 2 to make space for installs if it needs one.
But I had about 20 or 25 demos up until recently, I have 19 at the moment and they are all mostly big open world games that take up a lot of space. There is only a few really small ones.
And a few HD videos. And lots of photos and music. I do need to get a external hard drive soon though, because the one we had has been bust for a while and it wasn't compatable with the PS3.
