How much of the PS3's abilities do you use?

I was just flipping through the icons today and started thinking about it. As much as I use my PS3 i am really not tapping into it's full potential. I still use it off a cable modem instead of wifi, plan on changing that sometime real soon though. So far I have 11 full movies saved to my hardrive, 36 episodes of assorted tv shows, I have 8 games for PS3(4 of which are exclusive) I have like 20 demos, I rented a few movies off of PSN, downloaded an episode of Qore, use pictures i have saved as background, got 249 music files on it and much more...
