That was Sony's original apology to the masses for the hack (and the resulting month-long downtime). It's also how I got into inFamous, which I'm quite happy about. :-)
This is Sony offering actual financial recompense to people negatively affected. To the best of my knowledge, if my data was taken it wasn't used. By now the card that was in there is long since dead, and I haven't noticed any ill effects. Hopefully their competitors looked at the time that Sony took after the hack to secure their servers and quietly checked their own systems over before similar hacks could arrive.
