Isn't it also that non-slim owners can't go online? (didn't read the link BTW)
Good thing I have a slim, even though I have owned a PS3 for about 4 days, it's still unopened. I don't know when I should open it, I got it because it was selling out and didn't want to play the wild goose chase in about a week. (FFXIII
EDIT - People said it's back on.
