It's actually refreshing to see how well youtube works with the PS3, since so many flash sites don't run well on it at all.
Moreso than Playstation Life, I would love to see the browser updated. I wish they would add folders for the bookmarks and update the flash (I guess they can't since there is some issue with the SDK for consoles not being there or something of the sort).
Since PS3 already has printer functionality, I would love to see Sony port over openoffice if that was possible, since my laptop is a piece of garbage that cuts off all the time.
