Happy 20th ya little purple cube! I've still got mine plugged in and playing (finally finished Donkey Kong Jungle Beat) thanks to GCloader and a clock battery replacement
I bought mine as an adult too, and went to "parties" with it, we were essentially playing MKDD, timesplitters on one friend's PS2, and Halo on lan-connected Xboxes. it was wayyy easier to take along than my eMac.
