Everyone got: Sun office items like ballpen and notebook (not laptop), openSolaris CD, Sun Solaris CD, AMD CD, chinese Sun hong bao (small red chinese envelopes - because it coincides with the chinese new year week - a big week here in Singapore)
To lucky participants, e.g. those who asked questions during the lecture: T-shirts
To a few (around 2 or 3) lucky guys who came early, before 7:30am: top of the line laptops
To another few guys (around 2 or 3) : huge late model hd flat plasma screen tv
I think there was also a few iPhones given away.
But the best was to be away from work; and simply enjoy it.
